That's So Raven - Season 3 Episode 1 -

Raven, Chelsea, and Eddie give a student at school named Tyler a makeover. Tyler likes Raven, but he is not Raven's type, so she tells him that she just wants to be friends. After the makeover, Tyler turns out to be really handsome, so she wants him back. But he's already dating someone else. This causes Raven to disguise herself as a belly-dancer and -- unsuccessfully -- try to break them up at a restaurant.
