Patrick Stewart kisses Conan O'Brien on TV

Conan O'Brien and Patrick Stewart lock lips on TV.

Star Trek star Patrick Stewart went, possibly, where no man has gone before and kissed talk show Conan O'Brien on the lips.

Stewart recreated his same-sex lip-lock with gay, "intimate" friend Ian McKellen by planting one on O'Brien.

Stewart was discussing kissing his close friend McKellen on the red carpet when he walked around the O'Brien's desk, grabbed his cheeks and went for it.

"I felt passion," O'Brien said.

Stewart confessed he'd like to lock lips with another British knight, Sir Sean Connery, adding, "Maybe a bit of tongue there".
