"Criminal Minds" Season 11 is set to premiere on Sept. 30. Ahead of its premiere though, FBI Special Agent Derek Morgan actor Shemar Moore is busy helping to find cure for multiple sclerosis, a disease that has stricken his mother.

These days, Shemar is very active on social media as he asks his fans, called the baby girls, to help him in his endeavors to hasten the search for the cure against the immune system disease. On Thursday, he posted on Facebook an announcement for his baby girls to join him in The Beat MS Dance Walk at the Palisades Charter High School in Los Angeles, Calif.

Aside from sharing the promotional poster for the event, Moore also encouraged his fans and followers through his post which reads: "Continuing the fight for the cure!! Join me Saturday the 12th of Sept. as we dance and walk for the CURE!! The event is from 9am-1pm. We will have the BABY GIRL BOOTH rocking, along with music, dancing and lots of fun!!! For more info, to register and/or to get involved go to www.thebeatMS.com!!! See you there!!!"

Shemar is not the only celeb joining the event. It is stated in the poster that some of the people from "So You Think You Can Dance," America's Best Dance Crew," "Hit The Floor" and "Glee." His efforts to combat multiple sclerosis also extends to his personal website, where he sells his Baby Girl merchandise, which according to the "Criminal Minds" actor, is dedicated to helping eliminate multiple sclerosis and help support those who have the disease.

He frequently updates his Facebook account with posts of his Baby Girl of the Day, showing photos of his fans who bought any of his merchandise in support of him and his advocacy in finding cure for multiple sclerosis.

Shemar Moore is also recognized by the National Multiple Sclerosis Society. In the organization's website, Moore is listed as one of its ambassadors. "The Young and the Restless" actor even put together the MS 150 Bike Tour, and in 2006, he and his team which was primarily composed of his "Criminal Minds" costars rode 100 miles and raised over $20,000 for MS research and programs.

Moore's active participation in the multiple sclerosis research was reportedly triggered by his mother Marilyn's diagnosis of the disease in 1999.

Recalling the diagnosis in an August interview with People, Moore said, "I went through the whole denial thing for a couple of years. I was like, 'Take a couple aspirin and go to sleep...You'll be fine. You'll be fine. Go get a massage and slow down.'"

Speaking of the annual 100-mile Bike MS: Coastal Challenge, Shemar said, "People may see me as an advocate, and I guess I am, but I just don't see myself that way. I'm gonna ride that bike every year, as long as my body will allow it, and it will because I'm healthy, I don't have MS, and I'm gonna continue to hug my mother."

Last month, the "Criminal Minds" Season 11 actor was honored at the Southern California and Nevada Chapters of the National MS Society at the Dinner of Champions event.
