“Sittin’ Up in My Room” is a song by singer Brandy, written and produced by Kenneth “Babyface” Edmonds for the soundtrack of the 1995 motion picture Waiting to Exhale. The track was one out of five singles the album spawned and reached number-two on the US Billboard Hot 100, becoming Brandy’s most successful single on particular chart up to that point OH!

In the video, Brandy is swimming in thoughts of a guy, keeping herself penned up in a very trippy retro, cartoonish room after her friend (Kim Coles) told her that her love interest is joining the party, which is going on downstairs. Actor Donald Faison played her love interest in this music video, directed by Hype Williams.
