Who could have expected Robert Pattinson and Kristen Stewart to cross paths with each other at an airport out of all the places? The former Twilight couple was stuck on the same flight while jetting into Los Angeles on 7 July along with K-Stew's gorgeous new girlfriend Stella Maxwell.

While the ex-lovers didn't seem much pleased in the airport pictures, the unexpected reunion is said to have royally ticked off Pattinson's current girlfriend, English singer FKA Twigs. According to a gossip report, the songstress is "upset" as the Twilight stars have of late started communicating again.

A source told Life&Style magazine that Twigs – whose real name is Tahliah Debrett Barnett – wants her boyfriend to "break off contact" with Stewart.

Apparently, the 31-year-old Good Time actor had called up his ex for some career advice following the latest acclaim at the Cannes Film Festival.

"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," the unverified report claimed.

But the magazine source says "FKA is so jealous," even though "hooking up with his ex is the last thing on Rob's mind."

Pattinson and Stewart dated on and off during their Twilight days until the much popular pop culture couple decided to part ways in 2013. Since then, the exes have hardly been spotted together, with both moving on in each other's lives.

While Rob is said to have taken his relationship with Twigs to the next level with an engagement, the Personal Shopper actress enjoyed her fair share of romances. First, she was linked to Alicia Cargile, following which the actress was dating Cara Delevingne's ex-St Vincent. Most recently, K-Stew seems to be going strong with Victoria's Secret model amid romantic get-togethers and date nights.

In fact, the actress and the model were on their way back from Paris Fashion Week – where the two seemed inseparable – when Stewart and her ex Pattinson crossed paths.
