Watch Pink and her 9-year-old daughter sing adorable Christmas song together

Once again Willow has shown how she's taking after her musical mother.

Pink and her 9-year-old daughter performed a classic Christmas song for ABC's Disney Holiday Singalong together and it will make your heart melt.

The mother-daughter duo sang Nat King Cole's The Christmas Song (Chestnuts Roasting on an Open Fire) while standing in front of a Christmas tree - and well, Willow's voice is just the sweetest!

After Pink sings out the final notes she waves over her youngest child, 3-year-old Jameson and they all wave at the camera.

Pink's family wasn't the only famous brood to appear during the holiday special, which was hosted by Ryan Seacrest.

Crooner Michael Bublé was joined by his wife and children while he sang It's Beginning To Look A Lot Like Christmas.

So sweet!

Other Singalong acts include South-Korean boy band BTS, known best for their song Dynamite, who performed Santa Claus is Coming to Town, Adam Lambert singing Have Yourself a Merry Little Christmas, Katy Perry with I'll Be Home for Christmas and Cozy Little Christmas, Andrea Bocelli with Silent Night and more.
