The couple originally hired a theater company to help their children Pax, Knox, Vivienne, Shiloh, Maddox and Zahara learn to sing but Brad and Angelina soon joined in on the fun.
“Brad likes belting out a tune in front of the kids. Angelina thought it would be a fun way for the kids to practice their singing and the theater group have really helped,” a source said.
“They’ve only been round a couple of times but Brad and Ange hope to make it a regular thing during their stay in the UK.”
The kids chose to sing their favorite pop songs while Brad and Ange went for older, classic pop tunes.
