Lauren Alaina has recorded and is releasing a cover of the festive classic 'Grown Up Christmas List.' The digital song will be available on iTunes on Dec. 10 and it's for a cause that is of critical importance to the singer.

The song is being released in conjunction with the 26th anniversary of the Special Olympics' 'A Very Special Christmas' series.

The series raises money to directly support the Special Olympics programs, which aid those with mental disabilities.

Alaina's history with the organization is long, as she teamed up with her local chapter at age 11. She is one of its ambassadors, working throughout the year to bring awareness to its efforts. Her involvement is not limited to the holiday season.

It is also a cause that is very important to her, due to her personal experience.

'Growing up, I was very close with a cousin who had an intellectual disability, and it upset me when people all around me treated him differently," the singer said. "I feel blessed that I’m able to be so involved with a cause dear to my heart. Not only am I able to record one of my all-time favorite holiday songs for a great cause, but year-round, I’m able to visit schools across the country and talk to kids about creating acceptance and respect for all kids – regardless of any disability.'
