"I'm sure they opt out of singing I Kissed a Girl or Ur So Gay," said Katy. "But they're singing along to every other song on the record."

Dane Cook gains 445% this week on this week's Movers & Shakers after the promotion poster for his new movie, My Best Friend's Girl, was released.

"Although I'm not a marketing major, I have a bit of a trusted reputation after 18 years self promoting," he writes. "I'd like to inform you I had no say in this marketing campaign, but if I did, things would be different since it is obvious that this poster is boring/odd." Cook, 36, listed 10 dislikes about the poster and did not hold back. The funny and raunchy list included problems with the characters' looks, the set, his lips, head, skin and at number seven, he jokes about his hair saying, "It's actually a close up shot of Tom Selleck's Magnum P.I. mustache they photo-slapped on my noggin'."
