Twilight star Robert Pattinson is reportedly getting serious about his relationship with girlfriend FKA Twigs.

According to Life & Style magazine, the 28-year-old actor and the 26-year-old singer, whose real name is Tahliah Debrett Barnett, want to tie the knot soon.

"Rob's in love and he's serious about proposing," a source told the publication, according to Hollywood Life. "He's crazy about her. They are definitely talking marriage."

Twigs is Pattinson's first serious girlfriend since splitting with Twilight co-star Kristen Stewart.

Pattinson ended his four-year relationship with Stewart, after it was revealed that she cheated on him with married British director Rupert Sanders.

Meanwhile, the Remember Me actor's friends feel Twigs is a better match for him than the 24-year-old actress.

"They can all see that Rob and FKA's love is mutual," the insider said. "He's never been in love with anyone as artistic as her. He's never been this happy before!"

Twigs had previously opened up about her relationship with Pattinson in an interview with USA Today.

"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 said.
