Check Out This Mini Destiny's Child Reunion With Kelly Rowland and Michelle Williams

— -- All that was missing was Beyonce!

When former Destiny's Child members Kelly Rowland and Michelle Williams got together recently, they once again joined their voices, this time to serenade Rowland's 10-month-old Titan Jewell.

Fortunately for us, they captured the moment on video, which Rowland posted on Instagram Tuesday.

As the duo harmonized, baby Titan could be seen bouncing on Williams' lap and beaming up at his mama.

"Ok your turn, add a third, post the video and make sure you hashtag #TITANSsong #GO," Rowland captioned the video, encouraging fans to add to the melody.

Rowland has also spent time with her other BFF, Beyonce, since welcoming her first child with husband Tim Weatherspoon last November.

In March she told the "Meredith Vieira Show" that the pals had recently arranged a playdate with Titan and Beyonce's daughter Blue Ivy.

"Just the other day we were all able to sit down and have lunch together, and that always feels good," Rowland said, while joking that it wasn't all girlfriend time. "Titan’s screaming and Blue is probably climbing something," she told host Meredith Vieira.
