Lyrics:

Everybody's having a real good time
The man you're talking to is not yours, he's mine
Better chill out, hear what I'm saying
Before I stop the music playin'

[Chorus:]
It's my party, I'll start it, I'll end it
Baby, it's my party, I'm upset and offended

While I'm all alone, and the party's goin' strong
It's a celebration, to better our relation
A sudden flash in my vision
Rendezvousin' in the kitchen
Kit got lost, and I found him all involved
He was wearing a guilty face
He had his arms around her waist
And lipstick on his face

[Chorus]

Everybody's having a real good time
The man you're talking to is not yours, he's mine
Better chill out, hear what I'm saying
Before I stop the music playin'

Say you had too much to drink
Lost your head and couldn't think
A sudden flash in my vision
Rendezvousin' in the kitchen
Then you got lost, and I found you all involved
Wearing a guilty face
Had your arms around her waist
And lipstick on your face

[Cecil:] Oh, tell me what it is
[Chaka:] Ooh, you had lipstick on your face
[Cecil:] Oh, tell me what'd you see
[Chaka:] Rendezvousin' in the kitchen
[Cecil:] Oh baby, what it's gonna be
[Chaka:] Gonna stop this music playing
[Cecil:] Oh, do you trust in me
[Chaka:] It's very plain to see
