Have you seen two Grohls on stage at the most recent Foo Fighters shows recently?
No you're not seeing things! Violet Grohl (Dave's daughter) has been on tour with the band serving as a backup singer!
The 12 year old, who is a little musician herself, has joined the other backup singers on a few dates of the Foo tour so far and Dave couldn't be more proud! At all the shows he's given her some sort of adorable shout out which have been captured on video.
So great! While we don't know how long she will stay with the tour, it's great to see her helping her dad out!
