And it was a mini reunion for the singers on Tuesday evening when band members Kelly Rowland and Michelle Williams partied together at the Jaguar and Gilt celebrate #MyTurnToJa event.
The girls even sat in a red convertible sports car as they got involved with the bash at Hollywood's Siren Studios.
And it was a particularly special reunion as it was Michelle's 32nd birthday.
Beyonce, the third member of the popular girl group, was absent from the reunion while she continues her current tour but Michelle and Kelly didn't seem to mind as they had a long overdue catch up.
And they certainly looked Bootylicious like one of their many hit song titles as they dressed up for the evening out.
Michelle stunned in a vibrant green frock with cut out panelling showing off her toned midriff, while she wore her dark long locks down and curly.
Kelly, meanwhile, also posed in the flashy car with a big grin on her face as she dressed in a stone coloured cropped top, which she paired with a black leather skirt.
She accessorised with a chunky chain around her neck and sparkly earrings while her hair looked sleek and straight with her fringe down.
The girls looked in high spirits as they posed together at the party.
And they happily shared their evening with their Twitter fans as they showed off pictures of themselves posing at the event, and with Michelle blowing out candles on a birthday cake.
