Whats the name of this song that plays in "I now pronounce you Chuck and larry"?

ok so the song plays when they are in the halloween party at a club.
they are sitting on a table and then the song comes on and the lawyers
gay brother (the one dressed as a butterfly) says " thats my song! "
or "thats my jam!" or something like that and then he goes running to
the dancefloor.

Its sung by a female and i think it says something like "roses and
hearts" or something like that lol.

thanks in advance :). this has been driving me crazy lol
