Jennifer Lopez stepped out in this flashy Lanvin dress to announce her upcoming tour with Enrique Iglesias. The sleek pink, black and beige number hugged her famous figure in all the right places -- and so did that jewel-encrusted snake! Earlier this year, actress Emma Stone wore the same designer duds to W Magazine's Golden Globes party. While Emma let her hair loose and focused more on her smoldering eye makeup, J.Lo pulled her locks back into a ponytail and piled on the baubles, while keeping her face fresh.

After nearly two seasons as a judge on "American Idol," Jennifer Lopez may be calling it quits. The singer hinted that she may not return to the popular singing competition show in an interview on "The Ellen DeGeneres Show."

"I really do enjoy it," J.Lo told Ellen of the gig, which reportedly earns her a staggering $12 million each season. Despite the hefty paycheck, the working mother-of-two may have had her fill of the all-consuming commitment. "Now this is my second year -- I don't know if I can go for a third year," she admitted. "I miss doing other things. It really does lock you down, which was nice the first year with the babies being 3, but now they're getting more mobile, they're about to go into school ... So I just don't know."

J.Lo's confession follows some warm words of advice she gave to competitor show "The X Factor"s newest judges, Britney Spears and Demi Lovato. After hearing Lopez's confession about her uncertain future on "Idol," the advice seems more like a passing of the torch!

After both "American Idol"s Jennifer Lopez and "The X Factor"s Britney Spears were slammed for their lack of qualifications by "America's Got Talent"s newest judge Howard Stern, J.Lo has offered up some veteran advice for her future rival, who was officially announced as part of the Season 2 "X Factor" judges' panel alongside fellow newcomer Demi Lovato yesterday (May 14).

"Just be yourself," Lopez advised Britney via ET Online. "I think it's just about really being your true self, not trying to be something that you're not. I feel a little scared for them 'cause I was scared when I started," J.Lo, who will soon wrap her second cycle as an "Idol" judge, admitted.

Katy Perry switched her normally bright and bubbly look to Goth when she attended the NARM Music Biz Awards dinner party in Century City, Calif. this week (May 10). The pop star showed some skin in a cutout, bondage-inspired gown, which covered her enviable curves in mesh. Fellow singer Jennifer Lopez wore a very similar dress, with a shorter hemline, just weeks ago, for an episode of "American Idol." While both ladies rocked spike-embellished heels, Katy kept the entire look dark, with deep wine-colored lips, smoky eyes and a beaded crucifix hanging from her neck. Meanwhile, J.Lo let her curves do the talking, keeping her makeup fresh, and her hair and jewelry simple.

Controversial radio host Howard Stern has made a name for himself by always speaking his mind -- that, and asking women to take their tops off on TV. And while the new "America's Got Talent" judge promises to "tone down" his own act for the show's family audience, he insists he'll still be a much better judge than the stars on some of his competitor talent competitions. Stern slammed "The X Factor"s newest addition, Britney Spears and "American Idol"s Jennifer Lopez in one fell swoop during a recent "AGT" press conference.

"Well, I think it's a wonderful decision," Stern said sarcastically of the $15 million deal Spears just signed to become "The X Factor"s newest judge/mentor. "Britney still thinks the earth is flat," the 58-year-old said. "I don't anticipate great opinions from her," he continued before blasting Lopez, too. "I think she's gonna sit there like J.Lo, 'Oh, you're wonderful, you're terrific. You think I can get a perfume endorsement out of this?'"

"Before this movie ["What to Expect When You're Expecting"], it [adoption] wasn't something that had occurred to me. But after this movie, yes, I could see myself definitely doing it and being open to it for sure. Whereas, before I never thought about it really. When I held the baby for the first time -- our baby in the movie -- they were twins, they were two little twin Ethiopian boys. Their parents went through a similar thing, and actually have adopted before, and so we got to talk to them a lot about it too. But when you hold that baby, you can really see how easy it is to just love another child that is not yours. Really, such a simple thing." -- Jennifer Lopez

Star of the upcoming film "What to Expect When You're Expecting," Jennifer Lopez tells Access Hollywood that her latest film opened her up to the possibility of adopting a child. The mother of 4-year-old twins Maz and Emme said speaking with the adoptive parents of her on-screen baby, played by twins, opened her mind on the matter.

As Mother's Day approaches, celebrity mamas have opened up about their personal experiences raising children in the June issue of Redbook. One of those famous moms is Jennifer Lopez, who revealed that she suffered from a serious case of "the baby blues" after giving birth to twins Emme and Max.

"I remember after the babies were born, about seven to 10 days in, I was like, 'What is going on with me?'" J.Lo told the magazine. "I felt sad and depressed and thought the babies didn't love me." The singer turned to the popular parenting book, "What to Expect When You're Expecting" in order to figure out what was causing her postpartum paranoia.

Who: Wisin & Yandel featuring Jennifer Lopez

What: The music video for the new tourmates' studio collaboration, "Follow the Leader"

Why We Love It: After announcing that Puerto Rican reggaeton duo Wisin & Yandel would be the opening act for her co-headlining tour trek with Enrique Iglesias, J.Lo has teamed up with the Spanish-language rappers for a sexy new music video. Lopez, who co-wrote the track, shows off her athleticism in the action-packed visuals as she runs across rooftops -- while wearing a super-tight, sequined Gucci ensemble! She, of course, has the help of a rather convincing male stunt double! Contrary to previous speculation, the Acapulco, Mexico-shot video was directed by Jessy Terrero, not J.Lo's boyfriend Casper Smart.

As reported by The BoomBox, Jennifer Lopez, 42, has given her dancer boyfriend Casper Smart, 25, a big promotion.

For Smart's 25th birthday back in April (the same month J.Lo's erstwhile husband Marc Anthony filed for divorce), Lopez bought the youngster a Dodge Ram truck, and now she's giving him a new job as choreographer for her upcoming 20-date tour with Enrique Iglesias and Wisin Y Yandel.

Lopez announced the move during a press conference about the tour, her first (in her mind, anyway), on Monday (April 30), revealing that her young beau would be composing her moves.

LOS ANGELES (AP) - Jennifer Lopez, Enrique Iglesias and Wisin Y Yandel are touring together this summer.

Lopez and Iglesias announced Monday in Los Angeles that the 20-city MEGA concert tour will begin July 14 in Montreal.

"We are going to give you everything we got," Lopez said. "I think it's going to be one of the most historic tours ever. Because I don't know that there has ever been something ... where these Latinos have come together like this as family."

Iglesias said the tour will include individual hits as well as collaborative performances. "I have a bunch of songs with Wisin Y Yandel and obviously with Jennifer," he told the crowd.
