Twilight heartthrob Robert Pattinson is reportedly planning to invite former girlfriend American actress Kristen Stewart, to his wedding with FKA twigs.

According to Hollywood Life, the 26-year-old singer, whose real name is Tahliah Debrett Barnett, is comfortable with the 24-year-old Camp X-Ray star's presence on her big day with Pattinson.

"Twigs isn't sure why he would consider inviting Kristen to their wedding – considering the circumstances of their split," an insider told the website. "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," the source added. "She just thinks it's a little strange he would want her there for their special day after she hurt him so badly."

In 2012, Pattinson ended his relationship with Stewart, his Twilight co-star and girlfriend of four years, after it was confirmed that she cheated on him with British director Rupert Sanders.

Stewart and Sanders, who worked together on Snow White And The Huntsman, were photographed kissing in the Hollywood hills.

Pattinson and twigs are very open about their relationship.

At the Mercury Music Prize Awards, twigs was asked how her relationship with Pattinson was going, to which she replied: "Very good, thanks."

During an interview with The Guardian's magazine, The Observer, she went even further and called Pattinson "the man that I love."
