Lindsay Lohan's mother Dina has blasted rumors of a rift between her daughter and Ugly Betty star America Ferrera on the set of the hit show.

Recent reports suggested Lohan's guest role in the series had been cut because of tension between the pair. Sources told the New York Post Lohan brought an entourage onto the New York set with her, and that the actresses engaged in a power struggle over who was the biggest star.

However Dina Lohan insists the gossip is untrue, telling People.com, "It was just silly. America's a doll. And they said (Lindsay) brought a posse. It was my mother and myself, and (sister) Ali. It was not a posse."
