Justin Explains His Big Kiss on Jimmy Kimmel

Justin Timberlake has always been really private about his relationship with Jessica Biel, so when they engaged in some major PDA during a recent basketball game, it made headlines.

JT was a special guest on Jimmy Kimmel's show last night and the topic of conversation was, you guessed it, their big wet kiss.

"We're not actually that much of exhibitionists in front of 18,000 people," Timberlake said on Wednesday's Jimmy Kimmel Live!

"They were playing Sonny & Cher's 'I Got You Babe,'" Timberlake explained. "And we were watching all these sort of elderly people kiss -- it got kind of weird there for a second, I'm not going to lie -- but it was really endearing."

"And then they cut to Dustin Hoffman and his wife, and he planted an open mouth kiss on her that was, like, award-winning in its own way," he continued.

Then, Timberlake said, "they cut to us, and I was not to be undone. So I mounted my girlfriend in front of 18,000 people." Looking back he claims that it was one of "those moments where I should have made a better decision," but we thought it was hilarious.
