Mariska Hargitay takes her cute son August to a performance of Yo Gabba Gabba at Radio City Music Hall in New York City on Sunday (October 3).

The 46-year-old Law & Order: SVU actress joined Liev Schreiber and his son Alexander backstage after the show to meet the popular kids group.

Also that day, Mariska took August to the Ultimate Block Party in Central Park where they built towers of green blocks along with 50,000 other people!
