Jessica Simpson's Daughter Maxwell, 3, Teaches Her Mom How to Pose -- Plus, See How Big Ace and Jagger Are Now!

Jessica Simpson may already be a pro in front of the cameras, but it seems her 3-year-old daughter still offers up tips for how to pose for the perfect photo.

The business mogul took to Instagram to share a sweet snapshot with her mini-me, Maxwell, where the tiny tot is showing her famous mom to "be cool and kiss the camera."

In the pic, Jess and Maxi look like twins as they both push out their pouts for the camera.

The mother-of-two also posted a pic of her son and Ashlee Simpson's daughter, Jagger. Ace, 2, who looks cool in camo pants and a fedora, is seen giving his cousin a kiss on the head as she sports a huge grin.

Can you believe how big these cousins have gotten?!

Ashlee shared her own snap of her little one on the social media site, where she is fluttering her long lashes as she stares directly into the camera.

One thing's for sure, these sisters made gorgeous kids!

Jessica recently opened up about life with her kids and hubby Eric Johnson on "Today," saying, "Marriage is unbelievable. I couldn't be more in love, and he's given me two of the best blessings -- Maxwell and Ace -- I could possibly imagine."

"Having a boy and a girl, I'm—I'm blessed," she gushed. "They inspire me."

While Maxwell might look like Jess' mini-me, the singer revealed that her little girl is a firecracker. "She's feistier [than me]," she admitted. "I'm much more reserved, and she's very opinionated, even though she's 2. I mean, I'm opinionated, but I don't yell it in your face!"

We can't get enough of this adorable family, can you?!
