During a recent appearance on Andy Cohen's "Watch What Happens Live," comedian Dane Cook shared a "dumb" story pertaining to Jessica Simpson and revealed that Kate Hudson was his worst on-screen kiss.

Cook explained that while filming alongside Simpson for the film "Employee of the Month," the blonde-haired songstress asked, "Are we making a movie?''

"That was kind of dumb," Cook added.

Cook also revealed that his "My Best Friend's Girl" co-star Kate Hudson had bad breath during their kissing scene for the movie.

"I did a movie with her, 'My Best Friend's Girl,' and I think she purposely ate like a feast of onions before our scene," he revealed to Cohen. "I had to burn her on that one!"

The Daily Mail reports that Cook appeared on last Thursday's episode of "WWHL" alongside CNN correspondent Candy Crowley.

In addition to dissing Simpson and Hudson, Cook also dished on his sex life while touring and named his Hollywood man crush.

Despite his not-so-great experiences with Simpson and Hudson, Cook confessed to having sex with "a few hundred" college girls while touring on the road for his comedy tours.

He also named Gary Gulman as his biggest male comedic crush, ABC News reports.

"Who's funny? Who's a handsome young man?" he replied to the question regarding his man crush. "Gary Gulman," he finally answered.

Cook's appearance on "WWHL" was to promote his first comedy special in four years, "Troublemaker," which debuted on Showtime on Friday.

"All the mysteries of life will be revealed," Cook told People about the comedy special. "No, honestly, it was me ponying up my own cash and you'll get to watch something that I truly dreamed of."

In addition to creating the jokes for the special, Cook also revealed that the special marks his directorial debut, which he revealed was a "lot of pressure."
