Twilight star Kristen Stewart is dating Nicholas Hoult. The pair are reported to be inseparable after spending time together on and off the set of their new movie Equals. Kristen, 24 and Nicholas, 24, are said to have ”bonded” during filming. A source told HollywoodLife: ”Kristen and Nick are inseparable. They are constantly hanging out together when they aren’t on set. They’ve really bonded with each other and are like best friends now. It wouldn’t surprise any if us if it turns into something more serious, something romantic. When Kristen is on location for long periods of time, she usually has a good friend come stay with her but not this time cause she has Nick. They love playing practical jokes on the cast and crew, playing pool, just exploring and hanging out.” Nicholas previously dated The Hunger Games star Jennifer Lawrence, who is now linked to Coldplay frontman Chris Martin.
