Kristen Stewart has completely moved on from Robert Pattinson and is serious about her relationship with Nicholas Hoult.

Hoult and Academy Award winning actress Jennifer Lawrence, who were co-stars in the X-Men: Days of Future Past had split for the second time recently and blamed their difficult schedules for the breakup.

Soon after the couple's break-up news broke out, rumours emerged that the Warm Bodies star and the 24-year-old Twilight actress are dating.

According to Hollywood Life, Stewart and Hoult, who are currently working together in sci-flick Equals, have "really bonded with each other!"

"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," a source said.

"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," the insider added. "They love playing practical jokes on the cast and crew, playing pool, just exploring and hanging out."

Meanwhile, Pattinson is rumoured to be dating British singer FKA Twigs.

The 27-year-old Remember Me actor and the 26-year-old singer, whose real name is Tahliah Debrett Barnett, were recently pictured holding hands on Venice Beach, California.

"Rob is falling hard for Tahliah. He's just enamored with her beauty, creativity and confidence. He hasn't felt this way about someone since Kristen," another source told the website.
