Jamie Lynn Spears' 15-year-old daughter Maddie Watson is not a girl, not yet a woman.

Nonetheless, the Zoey 101 alum's oldest child—who she shares with ex Casey Aldridge—recently headed off to junior prom. As seen in photos shared on Instagram April 14, Maddie towered over her mom while posing in a one-shoulder gown from Alabama-based Twenty Twelve Formal Wear, which featured pink embellishments and a high slit.

She paired the Barbie-esque look with pointed ivory heels and a bouquet of colored roses from her date, who coordinated with her dress in a fuchsia tie and white boutonnière.

Maddie's big dance comes isn't the only milestone for the family, as her younger sister Ivey recently celebrated her sixth birthday. As Jamie Lynn—who shares Ivey with husband Jamie Watson—noted in an April 14 Instagram Story, "Busy weekend."

The 33-year-old jokingly added, "I'll post after a couple hundred naps." 

Indeed, Jamie Lynn often documents her daughters' big moments on social media. In August, she shared a behind-the-scenes look at Maddie's photo shoot for homecoming court, quoting Kris Jenner in the caption of her Instagram post, "'You're doing amazing, sweetie.'"

The Zoey 102 star also couldn't help but to rave over Maddie when her "miracle angel baby girl" turned 15 last June.

"Thank you God," Jamie Lynn captioned photos of the high schooler as a newborn, "for making me her mama."

 

And her love for her daughter is one reason Jamie Lynn has no time for online negativity. Her mama bear side came out last year when she saw how public scrutiny over drama with older sister Britney Spears affected Maddie. 

"I have to say I will absolutely not allow my children—especially my oldest daughter, who was very affected by all of it—I will not allow her to feel this way in her life," she told Variety. "My strength is out of the love for my children and wanting to make sure that I don't give way to anything other than what I know to be authentic and true."

Jamie Lynn added, "All I can focus on now is my girls, my husband and the work that I'm doing."
