Robert Pattinson spends the weekend partying without Kristen
The Twilight star spent the weekend at two different celebrity bashes - the first being the after-party for Natalie Portman's choreographer husband Benjamin Millepied's ballet Moving Parts on Saturday.
A source told E! News: "He was there the whole night. He came at 5:30pm and didn't leave until the end of the after party.
"He just seemed really relaxed and happy. He was drinking beer and puffing on an electronic cigarette."
Most people might leave it at that, but Rob - who usually avoids such star-studded events - then spent Sunday evening at Jimmy Kimmel's Soho House bash.
A party-goer said: "He arrived at about 11pm. Rob was with a male friend and they were both dressed down, Rob in a hat and leather jacket.
"They hung outside for most of the night...Rob chatted with a few different people throughout the night but was mellow and hung in a smaller group."
Rob, 26, appears to be on good form, showing no signs of his heartbreak after Kristen cheated on him in July.
The actress was forced to issue an apology after photos emerged of her in a romantic clinch with her Snow White And The Huntsman Director, Rupert Sanders, 41.
She said in a statement: "I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected.
"This momentary indiscretion has jeopardised the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry."
Though Rob quickly moved his things out of their LA home, he's now said to have forgiven Kristen after an emotional chat.
A source told The Sun On Sunday: "They pretty much decided they couldn't live without each other.
"Kristen poured her heart out to Robert and told him it was a one-off and a mistake."
