Spears' daughter, who suffered from a nearly fatal ATV accident just four months ago, was seen enjoying her herself on Sunday during her LSU-themed pool party.
On Instagram, Spears wrote of her little girl: "My baby is 9 years old today, and more then ever we realize how precious every day is. So, we have to thank these 2 HEROS John and Victoria are the first responders, who literally saved Maddie's life, and they were able to celebrate her another year of her life with us this past weekend!"
"We are so blessed today, and everyday with this little angel! HAPPY BIRTHDAY MADDIE," Britney Spears' little sister added of her daughter.
As seen in photos from the event, Maddie's pool party was filled with balloons sporting the number "9," as well as "HAPPY BIRTHDAY MADDIE."
The birthday bash also starred a two-tier white, purple and yellow cake topped with a sparkler candle for the birthday girl.
As readers know, Maddie was left in critical condition after accidentally driving her ATV into a pond, where she was submerged in for several minutes.
Jamie Lynn and her husband, Jamie Watson, failed to rescue Maddie before paramedics arrived on the scene.
When paramedics freed Maddie from the water, she was unconscious.
"We went to pull her out but we realized her head was stuck in something. At that point we didn't know what it was — the water was so dark. It was pond water," first responder Victoria Ragoonath said of the incident.
Miraculously, they were able to revive Maddie and fly her to a nearby hospital.
Now freshly 9-years-old, young Maddie has never looked better!
