Shemar is using his "baby girl" catchphrase for a good cause online by selling clothes with the phrase printed on them. The proceeds go towards research to fight the battle against multiple sclerosis.

Finding a cure for multiple sclerosis became a life mission for Shemar when his mother, Marilyn Wilson, was diagnosed with the disease in 1998.
Moore also helps raise money for the National Multiple Sclerosis Society by participating in a 100-mile bike race that raises funds for MS research.
