Proud mother Britney Spears shares son's school award pic

Britney Spears shared her son's success by posting an adorable shot of Sean Preston holding a school award.

"My son received an award at school today for being the best encourager!!" the 33-year-old pop star captioned the cute snapshot, in which the 10-year-old is beaming happily in a gray hoodie, holding the trophy in his hands.

The "Piece of Me" hitmaker has been spending plenty of quality time with her boys, whom she shares with ex-husband Kevin Federline.

The singer was recently in Las Vegas for her Piece of Me residency.
