Awkward!

Robert Pattinson ran into his ex-girlfriend Kristen Stewart and her new girlfriend Stella Maxwell at the one place where he couldn’t avoid her — on a plane! The former Twilight stars had an unofficial reunion on a flight from France to Los Angeles on Friday, July 7 — and it looked like they tried their best to ignore each other.

Kirsten, 27, and her supermodel girlfriend both looked super edgy and casual in outfits that showed off both of their super toned abs. Kristen rocked her short blonde buzz cut, while her 27-year-old girlfriend styled her long blonde locks in loose waves — and both ladies kept their sunglasses on as they left LAX.

Robert, 31, tried to go as incognito as possible in a blue baseball cap paired with a jacket, T-shirt, and jeans. He also kept his sunglasses on and his earbuds as he left the airport.

It’s unclear whether Robert and Kristen sat next to each other on the flight, and they weren’t seen leaving together even though sources exclusively revealed to Life & Style that the lines of communication have recently opened up between them since their 2013 split.

“Rob’s new flick, Good Time, has gotten a lot of buzz since the Cannes Film Festival,” the insider revealed. “He called to ask Kristen how he could keep that momentum going since a lot of the films he’s starred in lately haven’t attracted much attention.”

It seems like their newly rekindled friendship is harmless, especially since Kristen is in a committed relationship with Stella and Robert is currently dating English singer FKA twigs — but even though Stella doesn’t seem bothered by it, FKA is definitely upset and she wants Robert to “break off contact” with Kristen.

“FKA is so jealous,” the source continued. “But hooking up with his ex is the last thing on Rob’s mind.”
