The relationship between Robert Pattinson and FKA Twigs is reportedly continuing to blossom.

On Thursday, Us Weekly reported that the couple has exchanged promise rings. And as it turns out, the Twilight star was apparently the one who made this bold move.

"It was Rob's idea to get the rings," a source said. "They're 'we're in a committed relationship' rings."

The site then pointed out some romantic gestures that Pattinson has been doing for his British singing lady.

"FKA loves Rob because he is the nicest guy she's ever with," an insider shared. "Rob sends her flowers, handwritten notes, and mp3 files of that he's written for her- she says he's the sweetest guy on the planet."

The public probably shouldn't be too surprised in Pattinson gets down on one knee and asks Twigs to marry him someday. From the looks of their relationship, it sounds like these two are in it for the long run.

"It goes both ways," another source said. "He says this is the best relationship he has ever been in and he can see being in it for life. He admires and respects her."

Pattinson was previously in a relationship with movie actress Kristen Stewart. They became one of the most infamous couples in Hollywood, but now it appears that the two have gone their separate ways. There is no word if she is dating anyone else or not.
