Those Kardashian siblings pick such awesome mates, don’t you think? The latest in Kardashian dating news involves the Kardashian brother Rob, who’s now reportedly stuffing himself into a porn star - the one who played Serra Paylin in the “Who’s Nailin’ Paylin” video, to be exact.

Porn star, Lisa Ann broke the news to reporters today, claiming that she’s been teaching Rob all sorts of exciting things about sex for the past month, and that “He brings out the total cougar in me”.

Update: Rob’s sources are now insisting that Lisa’s story is completely untrue. The two did meet about a month ago, but they supposedly aren’t having sex. The friend added, “She wants a bit of fame right now. Rob is laughing it off!”
