Alex joined volunteers on the front desk at the Cheltenham Festival of Performing Arts.
The festival welcomed hundreds of young performers in over 300 categories including music, dance, speech and drama - including Alex's own children.
Writing on Facebook, Alex said:
"A *MASSIVE* thank you to all the volunteers who put on the Cheltenham Festival of Performing Arts this year.
"My own kids take part, and I have seen with my own eyes how getting on stage builds confidence and broadens horizons.
"One volunteer has been devoting *six hours a day* (!!) for several weeks on festival admin. Truly heroic. We are all hugely grateful."
