Kirsten Dunst Might Join Britney Soon?

Kirsten Dunst’s odd behavior recently has sparked rumors she is “on the verge of a breakdown.”

The starlet came late, left early, and “acted erratic” during a recent event at Sundance, according to insiders. The source added that friends of the actress made apologies on her behalf, saying, “Kirsten is not in a good place right now.”

Dunst, who split from Razorlight rocker boyfriend Johnny Borell last year, has not been photographed or spotted out in recent weeks. A rep for Dunst told us, “Kirsten is fine.”
