Robert Pattinson will reportedly be dating Tahliah Barnett AKA FKA Twigs at Coachella 2015 where the "Twilight" star's new girlfriend is part of the lineup. According to a report from Hollywood Life, some wonder if the actor's former flame and avid festival attendee Kristen Stewart is threatened about bumping into the controversial couple.

A source has revealed that Kristen Stewart is set to attend the annual music fest, which will kick off on April 11, Saturday.

"Tahliah (FKA twigs) is performing at Coachella, and Kristen is still going," the source reported.

While the "Still Alice" actress seems to be fine about how Robert Pattinson has been openly dating Tahliah Barnett, the source revealed that Kristen Stewart might still have mixed emotions about seeing them together at Coachella 2015.

"It's just weird for Kristen because Coachella was always her thing with Rob," the source shared.

"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," the source added.

Robert Pattinson has been dating Tahliah Barnett AKA FKA Twigs amid negative feedback from die-hard fans of the "Twilight" saga, most of whom are still hoping that Edward and Bella would end up together in real life.

However, the Hollywood Life report revealed that the lead actress of the phenomenal movie franchise actually likes the music of the "Two Weeks" singer.

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

"Maybe she'll bite the bullet and just go and see her performance and just face her fears head on. "

The Coachella 2015 lineup also includes Florence And The Machine, who is reportedly the ex-couple's favorite banc.

"She just wants to enjoy all the shows and music and doesn't want people making a big deal about it," the insider said.

"Her friends know to avoid the topic and will watch out for her at the festival."
