Allen was in the middle of Skype interview for MTV News when Morrison made a surprise appearance on the webcam. The two stars went on to explain the "funny story" of how the song made its way from 25-year-old Allen to 32-year-old Morrison without the two parties ever meeting.
"I got my hands on the song. It was an amazing song, and I didn't find out until a little later on that Kris was a writer on it," Morrison explains. "It was kind of strange, 'cause he didn't know either that I had done it," he adds.
"I had no idea," Allen chimed in. "I got an email from the other writers saying 'Urgent, urgent,' and then I read it, and it said that Matthew Morrison was going to sing the song, and I was pretty stoked about it." That explains the unplanned Morrison cameo in Allen's interview. "That's why we're here today. We thought we'd hang out," says Allen.
Between filming (and planning to direct) episodes of the hit show 'Glee,' Morrison is busy working on a solo album, recording with stars like Sir Elton John.
