Britney Spears' 30th birthday was December 2, but the singer blew out the candles on her birthday cake on Saturday, the final night of her Femme Fatale tour.
"Having an amazing time at the end of my tour," she Tweeted. "Belated bday party!"
Sons Sean Preston and Jayden James helped her mark her final night in San Juan.
Spears, who wrapped up her whirlwind concert extravaganza, said she's prepared for the holidays, as well. "Looks like my xmas list is complete!" she wrote.
Happy birthday, Britney!
Aside from wrapping presents, there may be one more item on Spears' holiday list. Sources say her boyfriend Jason Trawick, is ready to pop the question.
Widely credited with helping bring Brit back from the brink, her former agent (he's now just her partner in love) has been a constant in her life for years.
What her next career move is remains to be seen, but she's earned some rest after this tour - and hopefully she'll have plenty to celebrate this month!
