Could Selena Gomez be turning to Twitter to vent over Justin Bieber and Kendall Jenner’s recent dinner date?

The 22-year-old singer has not only un-followed her on-again, off-again boyfriend on Instagram following his outing at Paris Fashion Week with Jenner, but she also posted a pretty cryptic tweet on Oct. 1.

On Tuesday, Sept. 30, Bieber and Jenner were spotted grabbing dinner and drinking champagne at Ferdi. The singer – who tried to punch at a photographer while leaving the restaurant – recently vacationed with Gomez before flying off to Paris.

Later in the evening, Bieber posed for photos with Jenner, Kim Kardashian and Kris Jenner at the CR Fashion Book Party, as Gomez attended the event solo.

Gomez and Jenner were BFFs earlier in the year, attending the Coachella music festival together before having a falling out.
