Talk of the Town (1995)

Monika, the host of a daily radio call-in show on the verge of becoming a thirtysomething, has almost given up all hopes of finding the man of her dreams when her gay brother convinces her to try it one last time -- via a contact advertisement. Surprisingly, she finds some- one she instantly falls in love with, only to find out that her "Mr. Perfect" is already married -- to her best friend.
