The actor’s latest rumored romance? His Les Miserables co-star, Samantha Barks. The 22-year-old actress played Eponine opposite Russell’s Javert character in the Oscar-nominated musical. Apparently the two developed a "special relationship" on set, and by the time they got to the Oscars, things had really picked up. After the show, they hit up the after parties, where an insider says "she was continually touching his sleeve, giggling and sitting in awe of his every word, and he was lapping up every moment. It was electric watching them flirt, it was the buzz of the ball."
