Shortly after Javi popped the question, the father of two posted a photo on Instagram with his soon-to-be bride.
"I already knew it was happening," Kail told her producer Patrick after he flagged the recently uploaded image. "I didn't know he actually did it, but I knew it was going to happen."
"Are you going to congratulate him?" Patrick asked Kail.
Kail quickly responded with a "no" -- and offered a message to the two.
"Good luck," she stated, while flashing a peace sign. "He's been cheating on you since you were pregnant."
With that, she closed her car door, and the scene ended. But what do you think: Should Kail reach out to Lincoln's father and his fiancée on the heels of this life-changing news? Or should she not say anything? Offer your opinion, then keep watching Teen Mom 2 every Tuesday at 8/7c. Plus, check out our Teen Mom YouTube channel for more content.
