Britney Spears & Boys Cover Elle

Absolutely adorable! Britney Spears poses along side her color-coordinated cuties Sean Preston, 4, and Jayden James, 3, on the cover of the new issue of Elle magazine. The issue includes a few more pics of the superstar and her sons, including a gorgeous one of the threesome poolside.

The Toxic singer celebrated her 28th birthday yesterday by hitting the shops in LA with her agent beau Jason Trawick and then heading home to spend some time with her boys.

"Britney looked so happy. She seemed very excited to spend her morning with Jason," a source reported to People. Adds another, "Britney is very happy to spend the day with Preston and Jayden. The kids know it's her birthday... [They] are very excited about Britney's cake too."

Best wishes to her!
