+ Katy Perry's "Part Of Me" 3D film premieres tonight in Los Angeles, and MTV will be on the red carpet to ask her fan questions. Tweet @mtvnews questions with the hashtag #askkaty to participate. (MTV News)

+ One Direction and Ed Sheeran are heading to the studio. Sheeran will be producing the two-song session. "I wrote a couple of songs when I was 17 that One Direction want for their next album," Sheeran said. (MTV UK)

+ It's no secret that Adam Lambert has a lil disco influence, so it's no surprise he'd pay tribute to the late Donna Summer with a cover of "Hot Stuff." Well, and, he's hot stuff! Peep him performing "Never Close Our Eyes" and gettin' "Shady." (Idolator)

+ A Glambert twofer: watch Adam Lambert chat about being a role model and gay pride. "One of the things I find very gratifying now is that I have grown a lot more comfortable with my position and I'm embracing the opportunity to be able to address this stuff through music," he said. (Billboard)

+ Carly Rae Jepsen is Billboard's cover girl. She reveals she's currently writing a song in an unconventional way. "I ran into RedFoo from LMFAO at the airport, and we've been writing a song together today. Over the phone." Check out the Q&A. (Billboard)

+ Blur will be premiering new songs "The Puritan" and "Under The Westway" on a London roof on July 2, because, of course! Those of us not in London can catch the whole thing live via Twitter, by following @blurofficial. (MTV Newsroom)
