In the words of The Backstreet Boys, "Everybody (yeah), rock your body (yeah)," because it's time to celebrate baby Adalynn's birthday! This beautiful bundle of joy turns a whopping 1 year old on February 4, and she just celebrated her birthday with a killer party hosted by her parents, Teen Mom 2's Leah Messer and Jeremy Calvert.

Leah and Jeremy spared no expense when it came to their daughter's soiree — not only did she get showered with presents, she had not one, but two birthday cakes! Blessed.

It sounds like Addie had a blast celebrating her first year of life, and Leah hit up Twitter to share some special moments from her baby girl's big day.

"She was amazed [by] the balloons! LOL," Leah tweeted along with a few pictures, adding, "She's looks like she's thinking 'what the hell is going on?' LMAO."

Leah also revealed that Adalynn was "very interested in her presents" (um, who wouldn't be?!), which seem to have included a ball, an array of pink swag, and a giant tutu which girlfriend sported for the entire party.

It's hard to believe that Addie is already one — it seems like just yesterday that she made her grand debut into the dirty south! This little lady has made some major developmental strides in the last year, and amazingly she's already walking on her own two feet! Sigh, she must have inherited Leah's genius.

Make sure to wish Addie a happy birthday over on Leah's Twitter, and feel free to binge eat cheese puffs/lick a wall in her honor.
