Props to Robert Pattinson for being a loving, supportive boyfriend! The 28-year-old actor wanted to support girlfriend FKA Twigs Thursday when she performed at an Art: Basel: Miami Beach event at the National YoungArts Foundation campus. Because the event, co-hosted by III Points, was all about the “Two Weeks” singer, a source tells E! News that Rob watched his ladylove from backstage, allowing all eyes to focus on her! One onlooker said, “I don’t know that you really dance to her music, but Robert was swaying. It was adorable. He looked besotted with her and very proud.” A source added that once FKA wrapped things up onstage, Robert greeted her backstage with a huge hug and a kiss.
