It seems like Robert Pattinson is more serious with his current girlfriend, singer, FKA Twigs compared to his previous partner, Twilight co-star, Kirsten Stewart.

Last holiday season, Pattinson ended his relationship with Stewart when photos of Kirsten flirting with 'Snow White and The Huntsmen' director, Rupert Sanders surfaced online.

It was in September when Pattinson and FKA Twigs and sources say that the 28-year old actor was very happy. An insider tells Hollywood Life, "Rob is crazy about Tahliah. At first, he just had a big crush on her, but now he’s for sure falling in love with her. He wants to take Tahliah home for the holidays to meet his family and spend quality time with her,” the source continued.

The source also said that this is not a fling for Pattinson, "Rob said he could see himself spending the rest of his life with her. He has never ever said that about anyone, not even Kristen. He has found his forever soulmate,” Hollywood Life's source said.

Meanwhile, E! News' source reports, "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, but at this moment, Rob does want to spend more time in London."

The 26-year old singer opened up about her relationship with Rob saying that it was 'very good'. The brunette beauty also said, “I’m quite a shy person and I live in a constant state of shyness,” she told the publication. “My character on stage is a small part of my personality magnified.”

According to Grazia Daily UK, ”She is behind Rob’s decision to move back. He’s serious about her.” The source says, "They are really happy and he seems keen to make a fresh start, away from the mutual circles he shared with his ex-girlfriend Kristen [Stewart] in LA. They’ve both got busy schedules but they’re planning to move to London together in the foreseeable future.”
