January 16, 2013 - 09:38 GMT hellomagazine.com Robert Pattinson and Kristen Stewart: new claims of romance trouble after Twilight stars seem distant at golden Globes afterparty Twilight sweethearts Robert Pattinson and Kristen Stewert got their relationship back on track after she admitted a "momentary indiscretion" with Snow White and the Huntsman director Rupert Saunders, but the couple have been hit with new claims that all is not well in their relationship. Kristen didn't walk the red carpet with Rob at the Golden Globes at the weekend, though she did join him at the West Hollywood's Soho House private afterparty, well after midnight. The pair hardly put in a loved-up appearance at the bash, with one onlooker commenting that the pair: "hung around each other, but [they weren't] on top of each other." CLICK ON PHOTOS TO ENLARGE Robert had dressed up for the occasion in a smart suit, while Kristen kept things casual in jeans, a sweatshirt and a backwards trucker hat. There have been reports in the UK that Britain-born Robert called time on their relationship over Christmas, which they apparently spent apart. They did spend the thanksgiving break together, though, in the UK. They were last seen together in public in November, catching a flight out of New York's JFK airport. The couple's romance was thrust into the spotlight last summer when compromising pictures surfaced of Kristen and filmmaker Rupert, who is married to British model Liberty Ross. The couple have two children - Skyla, seven, and Tennyson, five. The brunette star then issued a public apology to her boyfriend. She said: "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 jeopardized 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." Kristen retreated from the spotlight for a while, but there was no such luxury for Rob, who hit the promotional trail for his David Kronenberg move Cosmopolis shortly after moving out of the couple's LA pad and spending time away at the California estate of his Water For Elephants co-star Reese Witherspoon. Friends maintained the couple "couldn't live without each other", though, and after a series of tearful phone calls, they apparently met up and decided to give things another go. The pair certainly seemed back on track as they attended their first red carpet event after claims of Kristen's infidelity, at the world premiere of Breaking Dawn: Part 2.
