Robert Pattinson and FKA Twigs are getting very serious.

E! News reported that the 28-year-old "Twilight" star introduced his special lady to his parents and sisters over the holidays. A source claimed that the actor's family loved the 26-year-old singer.

"They absolutely loved her," a source told E!. "It went so well. Rob's family has always been supportive of him and they thought they were great together."

Pattinson and Twigs, who were set up by friends Sienna Miller and Tom Sturridge, have been dating a little over four months and spending more time together. They were last seen together in December socking up some sun in Miami.

In November, FKA Twigs opened up to USA Today about her relationship with the Pattinson, saying being with the actor is "worth it," despite the negative remarks from his younger female fans.

Twigs added that she has no control over "14-year-old kids that should be in bed" instead of harassing people online. 

"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," she said. "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."
