Teen Mom star Leah Messer says that she slept with her ex-husband Jeremy Calvert. The Teen Mom 2 star, 26, opened up to close friend Kayla on Monday night's episode of the MTV show about her current relationship with ex-husband Jeremy Calvert. Messer told Kayla she was taken aback by an apology Calvert, 29, had made to her in last week's episode after he made comments in a past season about how he wished he never had a child with her, reports people.com.

"Jeremy also called me during the twins' birthday party. He was just letting me know that he regretted saying some things on TV that he didn't mean to say," Messer told Kayla. "One thing that he did say (at the time) was that he wished he would never had a child with me. And then he was thanking me for being such a good mom to Addy," she added.
