File:PandP; Brooke vs Ally - Princess Party.jpg

At what Ally, Trish, and Dez thinks is a second date with Austin and Chelsea, but in reality turns out to be a "princess party" for Chelsea's little sister Heidi, Brooke barges into the party uninvited, but dressed like a princess herself, declaring that she, not Ally will ruin Austin's date, in the episode "Princesses & Prizes."
