Kirsten won't be doing Spiderman 4

Kirsten Dunst will not be starring in the fourth instalment of the Spider-Man films.

According to sources, Dunst, 24, has developed quite an attitude since she began dating rocker Johnny Borrell. At the recent premiere of Spider-Man 3 in Tokyo, the young actress was asked about the possibility of a fourth film. She said, "Audiences aren't stupid. It'd be a big flop without me, Tobey or Sam."
