Sean Preston and Jayden James look thrilled with superstar mom Britney Spears who took them to see The Lion King at Mandalay Bay in Vegas! What a cute backstage photo with the cast members.

The pop star, in white sun dress and pink flip flops, was all smiles at the popular Disney musical with her young sons. Brit has been busy promoting her latest album Femme Fatale, and no doubt, loved taking a break!

Looks like the pint-sized cuties scored some plush Lion King souvenirs. Hakuna matata!
