Catfight?

This weekend, Drew Barrymore and Kirsten Dunst had an awkward run-in backstage on the set of Saturday Night Live, according to OK! Magazine. Drew was there to support her gal pal Cameron Diaz, while Kirsten was there for her Spider-Man co-star James Franco, who had been acting as host for the past week.

According to a source for the magazine, the encounter was so awkward, "James [Franco] had to deflect the situation by making a joke and walking away with Kirsten while Drew then fumed about it to Cameron."

After SNL, the drama continued at Wildwood Barbeque, where both actresses ended up after the show. A source for the mag reveals "Both Drew and Kirsten were there, but Kirsten didn't want to be near her, so they stayed far away from each other the entire night."

Drew split from boyfriend Justin Long back in July, and just weeks after the breakup, Justin was spotted out with Kirsten. This isn't the first time Kirsten has taken Drew's leftovers - remember her fling with Strokes drummer Fabrizio Moretti? That also happened just weeks after the Drew ended her romance with the rocker, so it's easy to see why Drew might be giving Kirsten dirty looks!
