'Teen Mom 2' Leah Messer Gives Custody to Corey: Ex Won't Let Twins See Mom in Rehab! [WATCH]

Teen Mom 2 star Leah Messer's custody battle with ex-husband, Corey Simms, has just gotten even nastier after the MTV star posted a sneak peek of an upcoming episode where the reality dad refuses to let his kids see their mother. Will this damage their relationship even further?

In the post on her official Facebook page, Leah shared an MTV video, apparently wanting to show her fans how Corey took control when she gave him custody of their twins, Ali and Aleeah, for a month. The mother of three had just admitted she needed to go to rehab for personal issues, but stopped short of saying it was due to drugs. Leah instructed her fans to "KEEP watching the show for COMPLETE details" in the comments section.

In the sad preview, Leah's mom, Dawn Spears, wants to take the girls to see their mother in rehab for Mother's Day. When she asks Corey if that is possible, he says no after she refuses to tell him where Leah is getting help.

Watch the video here:

Fans of the reality star took her side after she posted the clip. Here is what some had to say:

Melinda Sue Phelps: "She is doing better than most girls her age would do. They would just give up and walk away. At least she is taking the steps and making the effort to try. You don't kick a person while they are down. I mean I can see him trying to get them if she didn't try to help herself, but that's not the case here. Give her a break. He just wants to have a little family with his new gf. Messed up."

Alexis Shasteen: "It's all about control! He needs to put his feelings aside and think about the girls. Leah getting help will only benefit them. He should give her a pat on the back for recognizing she needs help!! Let them see their mother they need it and so does she!"

Judith Cl: "It is none of his business where she is. They are divorced, he needs to respect her wishes and let her do what she needs for her. If she wanted him to know where she was, she would have told him. They are going to see their mother, they have a custody agreement, so there should not be any issues. It is about him wanting to know more about his EX than what he needs too. It seems like he is still in love with her, more than he is about those kids...."

Angie Hernandez: "What an absolute d**k it's her day "Mother's Day" and yes she hasn't made the best choices in life but she's still a mother and kids will figure out on their own one day how good or bad their parent is its not up to u to deny them their other parent."

Do you think Corey should have let the twins see their mother for Mother's Day even though he didn't know where they were going?
