On Sunday (Dec. 1), Jason Aldean's third child and only son Memphis celebrated his big ol' 2nd birthday! Both Aldean and his wife, Brittany, shared loving birthday posts to their boy, who is their first child together.

"This kid has brought so much happiness into our family's life over the last couple years," Aldean wrote as a caption to a series of adorable photos of his young man. "I can't imagine life without him now."

Meanwhile, mom Brittany posted shots of what appeared to be a blowout Disney-themed birthday party, with Memphis and baby sister Navy dressed in matching Mickey and Minnie Mouse shirts (big sis Kendyl also donned a festive Minnie outfit).

Proud aunt and uncle/godparents Kasi and Chuck Wicks did the honors of dressing up in full-on character costumes to delight the kids. "It was truly a dream come true for him," Brittany said of her son's blowout bash.

Mom also had some tender words for Memphis on social media: "I tear up just about every time I look at you because I can’t believe god blessed me with such an amazing little guy," she wrote. "Thank you for making me a Mama and showing me the best kind of love...You are my world angel."

Aldean deliberately scaled back his touring in 2019 to be home with his family. He has just released a new album, 9, and he's set to hit the road in January for his 2020 We Back Tour, which is set to run through March.
