According to OK! things got tense backstage at Saturday Night Live when Drew Barrymore and Kirsten Dunst came face to face.

Drew recently split from actor Justin Long, and Kirsten has been seen out and about with Justin, so things couldn’t get more uncomfortable when they bumped into each other at SNL.

Drew was there to support Cameron Diaz, who was making a cameo on the show, while Kirsten was there to support friend James Franco, who was hosting the show.

“Drew and Kirsten had a really awkward run-in,” one witness tells OK!. “James had to deflect the situation by making a joke and walking away with Kirsten while Drew then fumed about it to Cameron.”

Later at the after party, things didn’t seem any better “Both Drew and Kirsten were there,” says one party-goer. “But Kirsten didn’t want to be near her, so they stayed far away from each other the entire night.”
