According to recent reports T-Pain leaked news that Robert Pattinson is engaged to his girlfriend, FKA Twigs after only five months of dating. The Robert Pattinson FKA Twigs wedding hit a bump now that rumors say Twilight star Kristen Stewart is on the guest list.

"Twigs isn't sure why he would consider inviting Kristen to their wedding - considering the circumstances of their split," an insider told HollywoodLife.com.

"She would find it difficult to invite someone who had cheated on her because she wouldn't really want to know that person anymore. But she's not against the idea of inviting Kristen. She just thinks it's a little strange he would want her there for their special day after she hurt him so badly."

The upcoming wedding of Robert Pattinson, 28, and "Two Weeks" singer FKA Twigs, 27, reportedly upset the 'Twilight' actor's co-star and ex-girlfriend, Kristen Stewart. In Touch magazine wrote that Robert Pattinson wants to put the wedding on hold because he misses Stewart.

According to People magazine, the wedding was actually postponed by Twigs.

"Rob told pals that he misses the wild life he had with Kristen," a source told In Touch magazine.

"Twigs is her polar opposite, which is part of the reason Rob loves her, but he can't help but miss all of the spur-of-the-moment things that he used to do with Kristen."

Kristen Stewart reportedly is moving on with her new girlfriend and personal assistant/roommate Alicia Cargile, but Pattinson hasn't gotten over Stewart.

"Rob says that he is still in love with Twigs, but he is not in love with the idea of marriage anymore," a source told In Touch.

"He is hoping for a very long engagement. Rob told pals that he misses the wild life he had with Kristen. Twigs is her polar opposite, which is part of the reason Rob loves her, but he can't help but miss all of the spur-of-the-moment things that he used to do with Kristen."

According to some reports, Pattinson's family prefers FKA Twigs over Kristen Stewart.

"Rob's family absolutely adores FKA twigs," an source told Hollywood Life last year.

"His sisters have never seen him happier. Both [sisters] Lizzy and Victoria totally approve of FKA twigs because they know how dedicated and committed she is to their brother. They love how easy going she is and how she really brings out the best in Rob -- he's never been so at peace and just blissful."

"They've never seen him more in love, not even with Kristen," the insider added.

"Lizzy has a strong connection with FKA twigs because they're both singers. What's impressive to Rob's sisters is that FKA twigs is interested in them and getting to know them. She's very engaging with them and Rob's parents, whereas Kristen was more reserved and closed off. They feel like FKA twigs has pure intentions and that her affection for Rob comes from the heart. They don't have any fears of her using Rob because of his fame or anything like that."
