Lifetime Television has tapped the Grammy Award-winning singer Mya for its 13th annual "Stop Breast Cancer for Life" campaign.

Mya, whose mother is a breast cancer survivor, sings the campaign's first-ever theme song -- "My Bra" -- written specifically for Lifetime's effort by multi-platinum songwriting sensation Kara DioGuardi (Christina Aguilera, Gwen Stefani, Celine Dion, Carrie Underwood, Faith Hill) and Grammy-winning producer/songwriter James Poyser (Common, The Roots/Erykah Badu, Lauryn Hill).

The song is featured in various on-air and online elements of the campaign, including its programming centerpiece, the specially-themed Lifetime Original Movie "Matters of Life & Dating," premiering Monday, October 22 at 9PM (ET/PT).

The movie stars Ricki Lake as a single woman living with breast cancer who relies on help from her friends, including co-star Holly Robinson Peete, who returns to the dating scene following her mastectomy.

All proceeds from the sale of "My Bra" will go towards breast cancer research. The song can be downloaded here.
