Boy, how times flies.
Britney spears turned 34 on Wednesday, and she celebrated with a surprise party.
Miley Cyrus was kind enough to send some giant, shiny balloons for the occasion.
"Had the CUTEST surprise party today!!! A special thank you to Miss @MileyCyrus for sending these awesome balloons!" Spears wrote on Instagram.
Here are some more snaps from Spears' 34th birthday party:
"Thank you so much for all the birthday wishes today! I loved reading them just as much as I loved my teacup cake," she wrote.
We recently found out that Britney Spears and Adele pretty much love each other, so that's nice.
