Tina took to Instagram to share a few photos from the party, one of them featuring her, Beyonce and Kelly together.
"3/4th of my girls. Missing 1/4 at Cochella," she captioned the photo.
The "missing 1/4" is her second daughter, Solange Knowles, who was at Coachella.
In the photo, Beyonce wore a white outfit which emphasized her baby bump, completed with sunglasses.
