The teenaged sisters will head back out with Spears for the European leg of the show next month, and admitted to being in awe of the singer's work ethic. "[We've learned] to have the eye of the tiger on stage," Destinee told AOL Music. "Every single song she does she just hits it, and she's just amazing. She always looks like she's having just the best time. We watched the show every night. We can't get enough, she's amazing!"
The twosome recently released the video for their new single 'True Love,' which has already received over 250,000 views on YouTube. "It's all about the beach," Paris added. "We are on the beach and we go into this dream and it's our version of a beach party. It's like in Madonna's video 'Vogue,' when you have all the different people doing different sorts of poses, and then you see us and we're on the sand and in front of this amazing background, it's awesome."
Destinee & Paris will head out with Spears starting Oct. 16. The tour will also feature singer Joe Jonas.
