During a season in which families come together, country star Keith Urban is working to bring some struggling parents joy this season.

Keith Urban & Nicole Kidman Are Not Having Twins 

On Tuesday The Boot announced that Urban will release a calendar to raise money for St. Jude Children's Research Hospital. The Somewhere In My Car singer first started the calendar project back in 2002 and over the last twelve years has raised over $850,000.

The 2015 calendar will feature photos taken by fans during his Raise 'Em Up Tour, with a different image from one of his concerts used for each month.

Why Keith urban Wants Nicole Kidman & Their Daughters To Watch 'American Idol' 

"I want to take a moment and thank every one of you who've been incredibly supportive, again, of St. Jude and the amazing work they do down there," Urban told fans on his site in 2012. "That raises so much money, but also a lot of awareness… and it's very, very touching to me how you guys always step up to the plate and help them out. Thank you for that, and God bless every one of you."

Helping out children in need is understandably an important cause for Urban. The singer himself has two daughters with wife and actress Nicole Kidman, six-year-old Sunday Rose and four-year-old Faith Margaret.

Earlier this month Urban was honored at the CMT Artists of the Year ceremony in Nashville, during which he emphasized the importance of his girls.

"Everything I do has purpose and meaning now like it never has before…" the singer said to his wife. "There's just real meaning in why I do what I do, and it's all for you and our girls."
