Babies New Year! Sweet Pics from Proud Mamas P!nk, Kelly Clarkson & Chrissy Teigen, Plus: 'Auntie' Kim Kardashian

Filled with the New Year's Eve spirit of embracing the future, some of the most famous moms in the world took to Instagram to show off their adorable tots.

Chrissy Teigen posted an infectiously funny video of daughter Luna, whose daddy is John Legend, giggling away as Mommy playfully scolds her, "Don't do it!"

P!nk posted an "Awww!"-inducing shot of her daughter with Carey Hart, Willow, holding her new little brother, Jameson Moon Hart. She captioned it, "Happy New Year 🎆 #newlove #newlife #newenergy #newhope #newday the harts thank you for your love ❤️ and we send it back to you in spades."

Looks like Willow shares her mother's affection for the color pink!

Not to be outdone, "American Idol" winner Kelly Clarkson showed off her daughter River Rose, 2, and son Remington Alexander, 8 months, with their daddy, Brandon Blackstock. She captioned it, "They're all mine.... 😊" — it's pretty clear she was laying claim to Brandon, too!

Finally, Mom Kim Kardashian has been shying away from social media ever since her traumatic robbery in Paris, but she happily posed with makeup guru Joyce Bonelli's newborn twin sons, giving them their first kisses "From Auntie KIKI💙".
