The ladies of Teen Mom and Teen Mom 2 have become pretty famous thanks to their gig as reality stars, and they're all about using their celebrity for a good cause!

While all the mommas and their boy toys do their part for charity, Teen Mom 2’s Kailyn Lowry, and Teen Mom’s Catelynn Lowell and Tyler Baltierra are taking it one step further. These three musketeers are getting together for a meet n' greet with fans at a Mom2Mom sale (sponsored by The LinkFund) in Cate and Ty's home state of Michigan on July 13!

Mom2Mom sales provide parents in the Detroit area with an opportunity to sell their unwanted kids clothing and toys, and donations from this particular sale will go to a 3-year-old cancer patient named Amie Strzalkowski.

This sweetheart has rhabdomyosarcoma, a rare form of cancer that she was diagnosed with before her second birthday. Unfortunately, Amie's parents fear she's showing signs of a returning tumor — despite the fact that she underwent surgery to remove the cancer in April.

“If I can do events like this and draw the public’s attention to a little girl in need, that’s what we were put in the spotlight to do,” Tyler recently told The Livingston Daily. “It’s one of those things that really tugs at the heartstrings and really motivates you to do something like this event.”

Catelynn and Tyler recently met Amie in person, and Cate added that "she’s got this personality that absolutely captures you, and it just made me want to help her and raise as much money as I possibly can to help this little girl.”

We expect a huge turnout at the event because Kailyn will also be signing copies of her best-selling memoir, Pride Over Pity. Hopefully, tons of money will be raised for little Amie, so if you're in the Detroit area, make sure to head over to Mt. Brighton from 8:30 a.m. to 4:00 p.m. on July 13 — admission is only $4!
