Celine Dion posts rare family pic, reveals her twins have cut their long hair

Looks like Celine Dion had a lovely Christmas with her kids.

The 48-year-old singer's team took to Instagram on Thursday to share a rare family photo of Dion with 15-year-old Rene-Charles and 6-year-old twins Eddy and Nelson, celebrating the holiday in adorably festive pajamas.

Dion revealed in December that she and her children would be celebrating the holidays in Montana, the family's annual tradition until last year, when her late husband, Rene Angelil, was too ill to travel. Angelil died last January after a long battle with throat cancer.

"He put something magic into that snow, into those mountains, and every time we go down, I go down with him," she told Page Six. "My children go down thinking about him. Every time I take the lift to go up, I feel closer to him."

Judging by Dion's sweet pic, she and her kids clearly had a fun-filled holiday -- and her twins appear to have cut their hair!

The young boys were last spotted with their waist-long locks during a trip to Disneyland for their sixth birthday in October.
