It’s been a big year for the Spears family. Britney scored herself a show at Planet Hollywood that’s turned into one of the biggest, most successful spectacles on the Las Vegas Strip while sister Jamie Lynn Spears got married!

Now in the latest bulletin from the pop star posse, Jamie’s little girl just celebrated a major birthday. She’s six! That’s two hands, you guys!

Maddie is Jamie Lynn’s daughter with ex Casey Aldridge and, in case you missed it, this mini-Spears has totally inherited her mom and aunt’s amazing vocal skills! That private concert happened back on Maddie’s birthday, June 19, and now we have even more photos from the special day.

Mama Jamie Lynn shared a couple of snaps from her daughter’s sixth birthday and the theme was just what we’d imagine for the perfect kid party in 2014: Frozen.

The former Disney star and her new hubby, James Watson, threw their little gal a shindig starring Anna, Elsa, and Kristoff complete with a delicious-looking snowflake-frosted cake and plenty of presents. Just check out that life-size cardboard cutout of Princess Elsa! What 6-year-old wouldn’t go nuts for that?!
