Lohan Wilde Child No More

Mamma Mia! starlet Amanda Seyfried is officially replacing Lindsay Lohan as flirty Mrs. Allonby in the big screen version of Oscar Wilde's play, A Woman of No Importance.

Svelte Lohan had been attached to play the leading role for several years. No word on why the switch was made, though it makes sense: Seyfried is a hot new face with a box office smash to her credit.

Lohan is best known now for her angry dad and explosive personal life.

Seyfried will co-star with Lord of the Rings Sean Bean, who plays promiscuous Lord Illingworth in the extravagant tale of betrayal.
