It looks like Teen Mom 2 star Leah Messer has patched things up with her ex-boyfriend Robbie Kidd just days after finalizing her divorce from Corey Simms in mid-June, according to UsMagazine.com. Following their ups and downs of parenting on the show, Messer, 19, and her ex-hubby Simms, 20, share custody of their 18-month-old twins, Aliannah and Aleeah.  However, Simms doesn’t seem to care much about having a family life with Messer. A source claims that Simms isn’t fazed by his ex’s new love and is “not interested in reconciling.”
