Until now on Teen Mom: Young and Pregnant, Kayla and Luke had a solid relationship. But after Kayla reveals in Season 3 that Luke cheated on her when she was pregnant and after she admits she still hasn't forgiven him, things take a turn for the worst. She also admits to meeting up with an ex. And although Luke's family thinks she hooked up with someone else, she denies it.

They aren't in a good place by the end of the season. But by all accounts, it looks like Kayla and Luke are still together after Teen Mom: Young and Pregnant.

Luke posts about Kayla pretty often on Instagram, and fellow cast member Brianna Jaramillo shared some Instagram photos from what appears to be a Los Angeles reunion. Luke and Kayla are together in one of the pictures.

Most fans are rooting for Kayla and Luke to move past their issues and work through it all for the sake of their relationship and their kids. They started out Season 3 with Luke's plans to adopt Kayla's son Izaiah from her previous relationship. Clearly, they want to keep their family together.
