Two 'Teen Mom' Couples Join Forces To Help A Young Cancer Patient

Catelynn and Tyler, plus Kailyn and Javi, attended an 'amazing' meet-and-greet to raise funds for little Amie.

Catelynn Lowell and Tyler Baltierra, as well as Kailyn Lowry-Marroquin and her husband Javi, spent the weekend doing their part to help a three-year-old who is battling a rare form of cancer.

The four familiar faces from "Teen Mom" and "Teen Mom 2" participated in a meet-and-greet and book signing for Kailyn's bestseller "Pride Over Pity" in Mt. Brighton, Michigan, on Sunday. The event was sponsored by The LinkFund, with all proceeds going to the family of the little girl, Amelie "Amie" Strzalkowski.

"Had such an awesome weekend with great people for a good cause!" Kail captioned the snapshot below. "Keep watching guys! So thankful I was able to be a part of something like this. Now we can give back in ways we never imagined. Thank you to everyone who invited us, who volunteered and who came out for the event! So much love!"

And speaking of the turnout, Tyler gushed about the overwhelming attendance. "This crowd is AMAZING!" he posted on Instagram. "Thank you all for coming out and supporting 3-year-old Amie with her battle through cancer...this is why we love what we do! @thelinkfund @catelynnmtv #MakeaDifference."

Javi echoed those sentiments with the tweet below:

As for the guest of honor, Cate shared a sweet embrace with Amie, while Tyler goofed around with the little lady.
