Dane Cook Gossips About Kate Hudson, Jessica Simpson: Reveals Simpsons Dumbest Remark

Dane Cook has been doing his promotional tour for his Showtime standup routine, Troublemaker (premiering tonight), where he told Andy Cohen on Watch What Happens Live, Thursday, Oct. 16 about his worst celebrity on-screen kiss and the dumbest thing his past costar Jessica Simpson ever said.

Cohen did a round of Q&A's with the controversial comedian, first asking his thoughts on the most overrated comic of all time.

"Over rated comedic of all time would be... Gallagher!" Cook, 42, responded, naming the comedian who is infamously known for his prop comedic routine and smashing watermelons as part of the act.

Next question got a little bit more personal, when Cohen asked who his worst on screen kiss was. His reply was shocking to most!

"Umm, Kate Hudson," Cook revealed. "Did a movie with her - My Best Friend's Girl- and I think she purposely ate a feast of onions right before the scene. I had to burn her on that one."

True or not (Cook is famous for outing his ex-girlfriends) we still love Kate- onion breath and all!

Cook has been a lucky man and has also starred in the 2006 Employee of the Month, with another top Hollywood lady, Jessica Simpson- famously known for her ditzy personality. So when asked about what the dumbest thing Simpson has said, Cook laughed. " I think she said one day, 'Are we making a movie?!'"

Troublemaker is cook's first original special in five years where he makes fun of all and every ex-girlfriend, modern day technology and much much more.

"I see the sparkle in my eye again, that maybe for a minute may have been diminished by some tough days. And I think it reflects in [the special." He tells Entertainment Weekly.
