Looks like the "Twilight" star is officially off the market after rapper T-Pain slipped in news of his engagement with FKA Twigs during an interview.

T-Pain accidentally told Vulture on April 1 that FKA Twigs and Robert Pattinson are engaged.

E! News noted that T-Pain has since tweeted to let everyone know it was an April Fools' Day joke, despite the fact that some still claim that the couple is really planning to walk down the aisle soon.

The rapper told the site that FKA Twigs is one of his favorite artists right now. T-Pain reportedly added that they first time met each other in the studio and her music has changed a lot since then.

"But she's always on tour," the rapper said, noting that she's in a different place everything he calls her.

Vulture was obviously surprised by the rapper's remark and followed-up if she's really engaged.

The rapper responded, "Yeah, to ol' Patty," he added, "I don't know if she wanted anybody to know that."

According to E! News, after noticing T-Pain's nickname for Robert, a new love was born and it became all that mattered as fans came up with some really funny tweets.

To add to the suspense, two sources close to the couple to People that FKA Twigs and Robert Pattinson are engaged. The magazine reported that Twigs has moved into Robert's home and, considering that they are already living together, it's not completely out of the question that they'd get engaged next. A friend of the British stars also told People earlier this month that they had exchanged promise rings.

The pal said, "He wants to marry her," further adding that "they are inseparable when they are together. They live at his house."
