Tons of crappy blogs are reporting that Robert Pattinson somehow had time to have one-nighter with Gossip Girl’s Leighton Meester. Despite no credible sources or back-up photos. Believe me, if Robert Pattinson was seen sneaking in or out of Leighton’s house..someone would have a picture of it.

Meanwhile…Star magazine reports that Kristen Stewart had a lovely birthday weekend in London with her sweetie.

the Twilight sweethearts rendezvoused for her 20th birthday on April 9 in Budapest, where he’s filming the period drama Bel Ami, then traveled together to London, arriving holding hands — until they saw waiting photographers! Then “they parted like the Red Sea,” says an eyewitness.

After visiting Rob’s parents in West London, it was on to a private hotel, where they holed up inside their room – and Rob could be heard playing his guitar and serenading Kristen.

“Their love is impossible to hide,” says an insider.

Another media source reports that Rob took Kristen home to visit with his parents before they shacked up in the hotel.

When did the “sickly skinny’ look become envogue again? Lindsay Lohan is rocking it now and so is the eternally unemployed Mischa Barton.

Mischa rocked a sick-French-vampire look at her birthday party in Paris this week.

Britney Spears celebrated her 27th birthday early on Saturday night with her London gay’s at a G.A.Y. event at British club Heaven.

Brit was in the U.K. for several television appearances including the talent show X Factor where she met up with stodgy old Simon Cowell. The boys presented the soon to be gay icon with a cake decorated to look like the cover of her new album Circus.

Britney is now headed back to the States for a birthday morning performance on Good Morning America this Tuesday, December 2.

And I know that Mick Jagger/Marianne Faithful tshirt is probably tourista-cheesy in London…but where I’m from that s*#t is funky fresh!
