She's on a musical roll!

FKA Twigs performed a sold out show at the Belasco Theater in downtown L.A. last night, and her doting fiancé Robert Pattinson was in the crowd as his lady love belted out her tunes. The British songstress got rave reviews for her Coachella set, so it seems her career is on the up and up!

We wonder when these lovebirds plan on tying the knot? They seem head over heels, so we bet there's a wedding sooner rather than later. What we're even more curious about is how Kristen Stewart feels about romance? Either she's secretly upset, or could care less now that she's dating her girlfriend Alicia Cargile!
