Just when you think Jessica Simpson's 4-year-old daughter Maxwell couldn't be anymore adorable, she goes horseback riding.

The doting mother shared a photo on Tuesday of Maxwell dressed like a little equestrian as she rode around on a horse. Simpson captioned the cute moment with a quote from her daughter. "I'm a Cowgirl Mommy!!!' - #MAXIDREW," she wrote.

Simpson's look-alike daughter is frequently featured on her mother's Instagram, along with her 3-year-old brother, Ace. Just last month, the 36-year-old singer shared a behind-the-scenes photo of her kids posing for their school photo, which looked more like a professional modeling shoot. "Seriously?!?!? Thank you God for these precious kiddos," she captioned the image.

While Simpson clearly loves motherhood, she told ET that she and husband Eric Johnson have no plans to expand their brood. "I don't think I could have another baby right now," she said. "It was a very, very big shock after having a baby and four months later knowing I was pregnant again, so I think that's not in our near future."

Simpson added, "But people have kids at 40 now, so you never know."
