Britney Spears has been working non-stop lately, doing all sorts video and photo shoots, as well as promo performances for her newest album 'Femme Fatale,' -- not to mention getting ready for a huge summer tour.

Despite her busy schedule, Britney spent some quality time with her sons this weekend in Las Vegas. She took Jayden, 4, and Sean, 5, to see a live production of Disney's 'The Lion King,' and the singer and her boys took the time to pose with some of the cast members.

Britney kept it casual in a simple white sun dress, while Sean and Jayden looked adorable in shorts, polos, and baseball caps. Check out these Britney Spears pictures of her day out on the town with her sons, and let us know if you agree that her boys look identical to mommy Spears!
