Britney Spears celebrates 30th birthday and tour end in San Juan

Twitter

“Having an amazing time at the end of my tour,” she Tweeted Friday, along with a photo of her blowing out the candles on a big birthday cake. “Belated bday party!”

Her birthday party was a belated one as she was born on December 2.

Besides entering her 30s, Spears had another reason to celebrate: her ambitious Femme Fatale tour came to an end at José Miguel Agrelot Coliseum on Saturday night.

The tour launched on June 16 in Sacramento, California, and covered a whopping 79 shows in all.

Now Spears is ready for the holidays after wrapping her Christmas shopping last week with the help of some of her 11,000,000-plus followers.

“Looks like my xmas list is complete. Thanks for all the great suggestions. Its been fun shopping with ya’ll,” she Tweeted.

And as the holiday season is nearing, sources say Britney’s boyfriend Jason Trawick, 39, may take the opportunity to pop the question.
