Are "Twilight" star Robert Pattinson and singer FKA twigs engaged?

People magazine said on Wednesday it had confirmed that the two, who have been seeing each other six months, are planning to wed.

The purported engagement comes after hip-hop artist T-Pain let slip during an interview with New York magazine's website that twigs, 27, was too busy to collaborate on his new album because she was engaged "to ol' Patty," referring to Pattinson.

He added, "I don't know if she wanted anybody to know that. . . . " Later, in an update, he claimed the remark had been an April Fool's joke. People said representatives for Pattinson, 28, and twigs have not commented.
