Paris, who was looking pretty hot herself, had nothing but nice things to say about Christina’s style.
She tweeted: “Love Christina Aguilera’s entire look! The hair, make up and outfit is sick!! She looks amazing!”
Paris was full of compliments for the other ladies.
She also said: “Sandra Bullock looked beautiful tonight.”, “Jennifer Lopez looked absolutely stunning” and even praised the boys: “Rob and Taylor are so hot!” – we’re guessing she means Pattinson and Lautner.
