Following his highly publicized split from Kristen Stewart back in 2012, it has been recently revealed that Robert Pattinson is now turned off by his ex-girlfriend.

Pattinson apparently does not find Stewart sexy anymore and is no longer attracted to her at all -- what is his reason? The "Still Alice" actress' short haircut. "Rob always preferred Kristen's hair on the long side, so he's not too impressed with her new short do. It's just not that sexy to him," a source revealed to HollywoodLife.com.

On the other hand, "The Rover" actor loves his current girlfriend FKA twigs' long locks, because he thinks it "really embraces her femininity, which is a real turn-on for Rob."

With that being said, things between the new British couple are seemingly getting serious. "Rob is crazy about Tahliah," another source told HollywoodLife.com. "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.

Robert Pattinson has clearly moved on from Kristen Stewart and feels that he has found the love of his life. "Rob said he could see himself spending the rest of his life with [FKA twigs]," the source said. "He has never ever said that about anyone, not even Kristen. He has found his forever soul mate."

Similarly, a source previously told Life & Style magazine that Pattinson is "serious about proposing" the "Video Girl" singer. "They are definitely talking marriage," an insider claimed. "All of Rob's friends can all see that Rob and FKA's love is mutual. He's never been in love with anyone as artistic as her. He's never been this happy before!"
