R Patz, 23, just can't handle the pressures of being famous.

He has been super vocal in the past about his hatred of screaming fans and mobbing crowds. So after he signed a few autographs at the London premier of his new movie "Remember Me" Robert decided to have a stiff one.. or two..

The heartthrob let loose in the uber posh Ivy Club in London's Convent Garden Wednesday night.

Robbie lad partied the night away with movie co-star Emilie De Ravin and a slew of guests.

After a few hours of fun and laughs (and no doubt one too many beverages) the star best known for his role as Edward Cullen in the "Twilight movies," was seen leaving the club at the back entrance, slightly loose on his feet but with a big smile on his face.

We all know that drunken smile R-man.

Pattison told the paparazzi he is till getting used to the crowds.

He said: "I never go to places where crowds congregate, so it's always a novelty. It's a completely separate aspect of my life. It's nice."

His real-life girlfriend Kristen Stewart, was not able to join him on the night. She was premiering her own film "The Runaways" in New York.
