The New York Post reports that Kim Kardashian's ex Ray J - the co-star in her sex tape that made her famous - met her husband Kris Humphries on a plane recently and congratulated him on his wedding.

The newspaper alleges that there was more than one minute of awkward silence after Ray J approached the basketball player. A source says that Kris pretended not to know Ray J.

However, the source claims that Kris relented after a few minutes. "Ray J said, 'Come on, you know who I am. I just want to say congratulations.' Then Kris, realizing he was cornered, said, 'Oh yeah, yeah, I’m sorry I know who you are.'"

Sounds like the beginning of a long plane ride!
