VIDEO: Leah Messer Wants to See if There's a 'Spark' With Jeremy Calvert in New 'Teen Mom 2' Episode

Teen Mom 2 star Leah Messer is learning the hard way that it is difficult to stay casual when hooking up with your ex-husband/baby daddy.

People reports that, on this week’s episode of the beloved MTV series, Leah takes off to Hawaii with her three daughters, twins Aliannah and Aleeah, nine, and six-year-old Adalynn, the latter of whom she shares with her on-again flame, Jeremy Calvert.

As Leah is driving to their vacation rental house, she talks to her mom about where things are with Jeremy. She admits that she invited her ex-husband of three years to join them on vacation, saying, “I was thinking if he came out here we would go by ourselves for a while. Any time we’re around each other, we’re around the kids. I don’t want them to pick up on anything that I’m not certain about yet.”

When her mom asks her if she thinks they could get back together, the reality star reveals, “We’ve been back and forth lately, and I don’t know where we stand. I want to see if the spark is still there,” adding later that she is fearful to take the first step. “My feelings could be more towards it if one of us makes a move, and I’m a little prideful so I’m not making any first moves,” the 27-year-old reality star divulges.

So, is Jeremy going to be the one to put himself out there first? I guess only time will tell what is to come for these potential lovebirds.
