Robert Pattinson and Kristen Stewart split: Actress fears awkward encounter with FKA twigs at Coachella 2015

American actress Kristen Stewart is reportedly worried about running into former boyfriend Robert Pattinson and FKA twigs at the Coachella Music Festival 2015 which kicks off on 10 April in Indio, California.

The 28-year-old Remember Me actor's singer girlfriend, whose real name is Tahliah Debrett Barnett, will be performing at this year's two-weekend long arts festival.

"Tahliah (FKA twigs) is performing at Coachella, and Kristen is still going. It's just weird for Kristen because Coachella was always her thing with Rob. It was such a fun time for them and something they always looked forward to when they were a couple. It's bittersweet for Kristen," a source told Hollywood Life.

"Kristen likes FKA's music, but it's not like she wants to be seen getting down to her music with Rob anywhere near."

"Maybe she'll bite the bullet and just go and see her performance and just face her fears head on. She just wants to enjoy all the shows and music and doesn't want people making a big deal about it. Her friends know to avoid the topic and will watch out for her at the festival," the insider added.

"Kristen would most likely go the first weekend because Florence and the Machine are playing Sunday (April 12) and FKA goes on Sat (April 11), so the chances of an awkward run-in with Rob are high," the source said.

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.

The pair had patched up their differences and started dating again, and were spotted together during Coachella Music Festival 2013.

However, the two broke up in May 2013 after Pattinson pulled out of his 27th birthday celebrations, which had been planned by Stewart.
