from www.usmagazine.com -How’s this for going rogue: A porn star who portrayed “Serra Paylin” in a famous X-rated film claims she is dating Kim Kardashian’s younger brother, Rob.

Lisa Ann, star of 2008’s “Who’s Nailin’ Paylin?” tells TMZ she and Rob, 22, met at an L.A. gym around the time of sister Khloe’s late September wedding. “Rob treats me like his little teacher and we have a fun sexual relationship that is simple and carefree,” she said.

But a source close to Rob tells Us Ann’s claims are “not true.”

Adds the insider, “They did meet at a gym, but that’s it. Never even hooked up. She wants a bit of fame right now. Rob is laughing it off!”

from http://blogs.timeslive.co.za – Yesterday I reported that reality star Rob Kardashian from Keeping Up With The Kardashians was reported by gossip site TMZ to be seeing porn star Lisa Ann.

Porn star Lisa Ann, who starred in the 2008’s Who’s Nailin’ Paylin? told the site that she and Rob, 22, met at an L.A. gym around the time of sister Khloe’s late September wedding also adding that the lad, “treats me like his little teacher and we have a fun sexual relationship that is simple and carefree.”

According to sources close to Rob,” Lisa Ann did meet Rob, but that’s it. Never even hooked up. She wants a bit of fame right now. Rob is laughing it off!”.

But in the turn of things, it seems Lisa Ann was not telling the truth nor is Rob laughing the matter off. Instead the livid Rob tweeted his feelings about the rumour saying he was “Seein The Blind Side with this whore/cunt/slut bi***!”

He also asked his sisters Kim and Khloe for some advice: “@KimKardashian @KhloeKardashian I dunno how you deal with lies from the tabloids!? Lies, lies, lies… Thanks for the publicity bi***es ,” he tweeted.

In turn his sister Kim told him to “get used to it” and said, “@RobKardashian U also can’t worry about what other people think…just live & be happy! Anyone that really knows u, knows the truth!”

Meanwhile, www.tmz.com reports:

The star of the “Nailin’ Paylin” porno considers her new hookup Rob Kardashian the “perfect little boy for a cougar” — but that don’t mean the two are gonna get monogamous any time soon.

Yesterday at the Sherman Oaks Galleria, porn star Lisa Ann said she hasn’t even met the Kardashian clan yet, because “people don’t really bring porn stars around their family” — and said marriage with the 22-year-old would “never happen.”

If a porn star and a Kardashian can’t find love … then who can??
