Robert Pattinson and Kristen Stewart split: Actor to throw surprise engagement party for FKA twigs

Robert Pattinson is reportedly planning to host an engagement party for girlfriend FKA twigs. Reports suggest that the couple got engaged last week.

According to the Sun newspaper, the 28-year-old Remember Me actor has invited few friends including Katy Perry to their rented mansion in Palm Springs.

"Rob has arranged for their closest friends to surprise her at their mansion," a source said.

"He's got a party planner to book dancers for the pool area and a cocktail maker. It's the first chance they've had to toast their engagement with friends so it should be a big night for them," the insider added.

It was previously reported that Pattinson is planning to invite former girlfriend American actress Kristen Stewart, to his wedding with the 26-year-old singer, whose real name is Tahliah Debrett Barnett.

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.

The 24-year-old Camp X-Ray star and Sanders, who worked together on Snow White And The Huntsman, were photographed kissing in the Hollywood hills.

Meanwhile, it was earlier reported that Pattinson and twigs are wearing promise rings.

"They picked the rings out together. Rob wanted to give Tahliah a promise ring over the holidays, but couldn't find the right one so he held off," a source told Hollywood Life. "They had been looking at rings together since the beginning of the year. It's like a pre-engagement ring. Very authentic and one of a kind."
