Robert Pattinson can't seem to keep his hand to himself. An update to the "Twilight" star's 2014 love affair with FKA Twigs includes PDA of some sorts. According to E! News, the former Vampire heartthrob grabs his girlfriend's behind after holding her hand during a walk.

Reportedly, the incident happened few days after FKA Twigs admitted that dating R.Pattz "isn't exactly easy."

"I really enjoy the fun of putting something out and people liking it or hating it or talking about it, but vacuous attention, it feels disgusting. It's like a hangover. It's weird. I know that's not really because of me or what I'm doing, [but] the positivity that I get from [my relationship] makes the more challenging aspects...very worth it," she told USA Today.

"I don't want to be in front of the camera forever," Twigs revealed in the new issue of Rolling Stone. "I'm not thirsty. I'm not a pop star. I don't want to reign over all forever. I don't want to be famous! It makes me feel sick, the thought of being a famous person. It's just not me. I'm the happiest when I'm in the studio, not on a beauty parade," she added.

E! News previously reported that a source close to the couple said that things "are getting pretty serious" between the two of them. The insider said Robert is considering moving back to London for now.

"He hasn't made up his mind if he wants to move out of L.A. permanently. He always says he will, but never does," the source explained. "At this moment, Rob does want to spend more time in London."

Mirror noted that the actor think he "might be done with Los Angeles."

"I've just realised that in the past few weeks. If you are the kind of person who needs to be pushed into doing something, then Hollywood is not the right place. I think I need to spend more time in London, or just move around a bit more," the actor said.

Reportedly, the "Twilight" star is eager to move back to England to find a new home with his lady love.
