Good Charlotte rocker Joel Madden and his partner Nicole Richie showed off their fun side on Saturday (27Nov10), taking to the stage in Los Angeles to perform in a popular children's show.
The couple took their kids, two-year-old Harlow, and Sparrow, 14 months, to the Yo Gabba Gabba! Live! There's A Party In My City concert - and they couldn't resist joining in the fun themselves.
Madden and his socialite fiancee performed choreographed dance moves on stage with characters from the pre-school series at the city's Nokia Theatre, much to the delight of young audience members.
The show was a star-studded affair - Gwen Stefani took her two sons, Kingston, four, and two-year-old Zuma, while Jessica Alba attended with her two-year-old daughter Honor.
