New York, Feb 3 : Speculations are rife that 'Spiderman' beauty Kirsten Dunst is on the verge of a breakdown, as she has reportedly been seen showing strange behaviour.

Sources have revealed that the 25-year-old star came late, left early, and "acted erratic" during a recent event at Sundance.

Dunst's behaviour even compelled her friends' to make apologies on her behalf, add sources.

"Kirsten is not in a good place right now," The New York Post quoted a source as telling of what Dunst's friends said.

The Golden Globe nominated actress has not been spotted out or photographed in recent weeks.

Her representative, however, insists that "Kirsten is fine".

Dunst had split with Razorlight rocker boyfriend Johnny Borell last year.
