Are Teen Mom’s Kailyn, Ex Jo Back Together?

They've been locked in a nasty battle over child support on MTV's Teen Mom, but on Tuesday's all-new episode, warring exes Kailyn Lowry and Jonathan "Jo" Rivera just may have finally mended fences.

As this exclusive preview clip shows, Lowry and Rivera — parents to Isaac, 2 — are able to put their differences aside to give their son a bath and read him a bedtime story.

And their togetherness doesn't end there. After Rivera tells Lowry he's willing to drop his appeal to lower child support payments, Lowry — currently dating Jordan Wenner — asks him to spend the night.

Find out his shocking response in the Teen Mom 2 clip above before the full episode airs Tuesday at 10 p.m. (EST) on MTV.
