Things are getting serious between Robert Pattinson and girlfriend FKA Twigs. A source close to the couple told People that after just a few months of dating they are so crazy for one another that they’re wearing promise rings. The insider claims Pattinson is ready to settle down with Twigs and that this relationship has changed him as a person.

“He wants to marry her,” the source said, asserting that Pattinson is “much more calm and happy than before.”

The 28-year-old former “Twilight” star and his musician girlfriend were first spotted together around Hollywood last September. Shortly after their initial sightings as a couple, Pattinson joined FKA Twigs on the European leg of her tour. They then jetted to Miami for Art Basel, where they couldn't’t keep their hands off of one another.

“They are inseparable when they are together. They live at his house,” the source added.

Though the two have been together less than a year and have been splitting their time between Los Angeles and London, this may just be a match made in heaven. Sources told E! News their shared passion for music, among other things, keeps them closer than ever.

“There is such a special connection between the two of them. Music is a big part of the relationship, because it means so much to them,” another source revealed. “They clicked instantly and they literally have become inseparable.”

“Rob loves her music,” the source added.

That explains why Pattinson has been spotted at so many of his talented girlfriend’s recent gigs! Unfortunately he was forced to miss FKA Twigs' epic performance at the 2015 Brit Awards last week. He did, however, make it to the after-party, where they were reportedly all over each other.

The actor even brought Twigs home to meet his family during the holidays. Though this is generally a nerve-wracking experience, the source claims it couldn't have gone better.

“They absolutely loved her,” another insider told E! “It went so well. Rob’s family has always been supportive of him and they thought they were great together.”
