Justin Bieber will release a love song "Turn To You" tomorrow for the most important woman in his life - his mother, Pattie Mallete.

He tweeted earlier today, ""#24HOURS until #TurnToYou on ITUNES for all the single moms out there. love u @studiomama."

The money raised from the song will help support single moms through the Bethesda Centre. Pattie Mallete had found hope through the Bethesda Centre in London, Ontario when she was a teen and pregnant with Bieber. It's a place that offers accommodation, counseling and support throughout and after pregnancy for young single mothers.

On www.savebethesda.org, Pattie shares, "If it weren't for Bethesda, I'm not sure where Justin or I would be. Bethesda gave us a chance."

Bieber told MTV, ""[It's] about the struggles, I say in the song. She had me at like the age I am now. [It's about] just the struggles she went through and how brave she was, and I think the world needed to know that."
