Sparks flew backstage at Saturday Night Live. This is all about a man. Justin Long the “I’m a Mac” commercial guy no less. Drew Barrymore who recently split from Justin was hanging out at SNL with good pal and “Charlie’s Angels” co-star Cameron Diaz. Well Kirsten Dunst was there cheering on SNL host James Franco her “Spiderman” co-star. Dunst and Long have been spotted out and about together getting very cozy.

“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 in the evening at NYC hotspot Wildwood Barbeque the cast and musical quests Kings of Leon with a sprinkling of other celebs like Blake Lively and Chace Crawford had an after party. Tension was thick and heavy in the air when ever the two came anywhere near each other.

Now this not the first time Dunst has scooped up Drew’s leftovers. Remember ‘The Strokes’ drummer Fabrizio Moretti? Dunst picked him up just weeks after his split with Drew too.

Come on ladies [and I use that term loosely here] all this over the Mac guy? Drew, Kristen just got out of rehab let her have him.
