Washington, Apr 24 : Pop singer Justin Timberlake has revealed his make-out session with actress Jessica Biel at the Lakers game on April 21.

Timberlake, 28, said that he and Biel, 27, were not usually in the habit of displaying their affection in public, but they were so caught up in the moment that they were not able to stop themselves.

"We're not actually that much of exhibitionists in front of 18,000 people," Us magazine quoted Timberlake as saying on Jimmy Kimmel Live!

"They were playing Sonny & Cher's `I Got You Babe'.

"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.

"Then they cut to us, and I was not to be undone. So I mounted my girlfriend in front of 18,000 people," he explained.

Thinking back about what he had done, Timberlake ruefully said he should have thought better.

"That was one of those moments where I should have made a better decision," he added. (ANI)
