Who knew Xtina was such a big fan of RiRi?!

Christina Aguilera and boyfriend Matthew Rutler attended the Rihanna concert last night, and the former Voice coach had nothing but nice things to say about the "Diamonds" singer. We love ladies that support each other!

Asked what the blonde bombshell's favorite song of the Barbadian beauty's was, she replied: "Everything. I love her!"

Something she did not want to comment on? How she thought the new coaches on The Voice were doing this season!

This couple might be happy in love, but one thing they can't agree on is a favorite baseball team! She wore a Yankees cap, while her beau rocked a Dodgers hat.

We bet this dirty girl danced up a storm at the show!
