Robert Pattinson & Rihanna? Sorry Kristen Stewart, 'Twilight' Hottie Parties with New Girlfriend FKA Twigs & Drake's Ex in NYC! [PHOTOS]

Robert Pattinson's one lucky guy! The "Twilight" heartthrob's new girlfriend FKA Twigs just had a stellar, sold-out performance at NYC's legendary Terminal 5 over the weekend:

Being the ever-so-loyal boyfriend, R-Patz showed his pride and support by taking Twigs for a night out on the town following the show. The couple was spotted partying together at the Manhattan hot-spot, Melrose Ballroom. Fellow pop beauty Rihanna was there, too!

Earlier on in the evening, RiRi partcipated in the city's "drag and dance" inspired fashion event, Mugler Ball:

Pattinson and his "Two Weeks" muse were caught cuddling throughout the night's festivities. Check out more photos from the star-studded evening here (via Daily Mail).

Things are definitely heating-up between Twigs and Kristen Stewart's ex (their relationship first went public back in September).

And the rumors are false - Pattinson is not getting back together with the "Camp X-Ray" beauty. He appears perfectly content with his new budding romance!

Meanwhile, rapper Drake's ex remains single... she's currently focused on the upcoming release of a new album (allegedly).
