VIDEO : Miley Cyrus' Awesome Birthday Gift for Britney Spears

Everyone and anyone must concede the title of ?Best Britney Gift-Giver? to Miley Cyrus, who pretty much one-upped everyone with one hell of a giant surprise. The Birthday Queen shared a few photos from her surprise party on Instagram, including one group shot with her friends and family (including her two adorable sons, Sean and Jayden). Britney captioned the pic, ?Had the CUTEST surprise party today!!! A special thank you to Miss @MileyCyrus for sending these awesome balloons!?
