While Kayla welcomed her first child, son Izaiah, with ex-boyfriend Stephan Alexander, she welcomed her second child, daughter Ariah, with Luke, who she has been with since 2019.
And although their relationship has had its ups and downs over the past three seasons, fans were hopeful that they would eventually tie the knot.
But others are less optimistic and believe that behind the scenes, the couple actually broke up and are only pretending to be together for the kids. Could that be true? Keep scrolling as we investigate.
Are Kayla and Luke still together, or are the 'Young and Pregnant' stars over?
Kayla and Luke's relationship does seems to undergo a major change in the new season. In a preview clip seen below, Kayla and Luke are at dinner when he seems to ask her an important question — with a diamond on the ready. However, Kayla is overheard saying, "Oh my God. Don't do this."
While that doesn't sound too promising, Distractify recently spoke with Kayla about what's going on between them.
"I can’t spoil the season and say where Luke and I are currently, but I will say there’s a lot of ups and downs with us this season," she told us, adding, "I think how we end up will shock a lot of people."
This information could confirm fans' theories that they broke up (in fact, it could have been right after he proposed!). After all, Kayla didn't seem very happy when they moved to Dubuque, Iowa last season so he could pursue his basketball dreams.
While Luke was supposed to be shooting hoops, he would sometimes stay out late drinking.
"I just feel like either way, I lose ... If I stay out here, I lose because I'm lonely and s--t. If I go back to DeKalb, I don't get to be with you," Kayla previously told him as the fog began to clear on what many fans thought was a strong relationship.
We also can't forget that Luke cheated on Kayla when she was pregnant with Ariah.
How long have 'Teen Mom: Young and Pregnant' stars Kayla and Luke known each other?
As Kayla explained in a previous interview with Ashley's Reality Roundup, she and Luke have known each other since high school, but they only started dating once her turbulent relationship with her ex-boyfriend, Stephan, was over for good.
"We did go to high school together, but we never really talked too much because I was dating Stephan my whole high school ... Stephan does know him, too, but they’re not really friends," Kayla told Ashley's Reality Roundup.
While they do have a lot of history together, it's unclear whether that's enough to keep them together. Especially since Kayla hasn't posted a photo with him on Instagram since late 2021...
