Taking a break from her NBC show The Voice, Christina Aguilera had a fun outing planned with 4-year-old son Max. The mother-son duo headed to L.A.’s Kodak Theatre, where they caught Cirque du Soleil’s film-themed show Iris together.
During intermission, the pop star and her son popped backstage to greet some of the performers. – and a source tells us they loved the show.
And it’s not the first Cirque du Soleil experience for Max, either. In January, Aguilera took him to their Michael Jackson: The Immortal World Tour show in L.A. along with her beau Matt Rutler. – Elizabeth Leonard
