Britney Spears

The proud mama took to Instagram to show off her sons Sean Preston and Jayden James.

Whoa! Britney Spears' sons are not babies anymore!

Brit and her brood have been enjoying the warm, (officially) Summer weather, and looking super cute! Britney — aka the Queen of Pop — posted this pic on Instagram yesterday, and we can't believe how big Sean Preston, 8, and Jayden James, 7, have gotten.

"What's up summer!!!," the picture is captioned. "Where are my sunglasses when I need them? Lol."

We can never find our sunnies either, Brit. (P.S. We're loving those beachy blonde locks!)
