The other day T-Pain let it slip that Rob Pattinson and lady love FKA Twigs were engaged, but seeing as it was April Fools' Day, we didn't take it too seriously. But we should have, because Us Weekly has confirmed that the Twilight hunk did in fact pop the question to his girlfriend of six months!

The couple exchanged promise rings in March, but now a source tells the mag that it was actually an engagement ring! "They only told a few people about the engagement," the insider tells the publication, adding, "They've been inseparable. He's planning on going to Coachella to support her ... They've been living together and he's been calling her his greatest love."

Pattinson famously split from his Twilight co-star Kristen Stewart in 2013 after several years of dating. She was busted cheating on him with her Snow White and the Huntsman director Rupert Sanders in 2012, but the two briefly rekindled their romance in an attempt to work it out after her affair. K. Stew has been with her pal Alicia Cargile for quite some time now, though she's never confirmed that the ladies are in a relationship.
