What happens in Vegas doesn’t stay in Vegas! On this week’s Teen Mom OG, Amber Portwood’s fiancé Matt Baier slams her for refusing to elope while in Las Vegas for a friend’s wedding.

After breaking down while trying on a wedding dress last week, Portwood continues to have cold feet about tying the knot with her controversial fiancé.

“It’s hard to just forget things,” Portwood told her friend. “I can forgive more easily than I can forget. I just want Matt and I to be in a place where the trust is completely there before we start planning and getting married. If any more surprises come out he’s going to lose something he’s never going to find again.”

Despite her concerns, Baier insisted they get married in Vegas. He even asked Portwood’s 8-year-old daughter Leah with ex Gary Shirley for her permission.

“I cannot get married without her,” Portwood said, as he responded, “I’m just playing around about it. You don’t have to embarrass me in front of everybody.”

But Baier wasn’t joking, as he asked her again when they were looking at chapels.

“Honey I want to get married here,” he said. “What do you say baby? Let’s do it. Let’s just f*****g do it.”

A “petrified” Portwood broke down in tears and insisted she ask her family for permission.

Her brother Shawn said on the phone, “It’s kind of not cool. You’re a big girl. At the end of the day, I’m not making your decisions for you. It’s not my life.”

Portwood then told Baier, “My family means a lot when it comes to this stuff. You know how close my brother and me are. You know how I feel about it. You’re really making me feel bad. I just want Leah by my side.”

Baier then insisted that he would never be unfaithful.

As Breaking Celebrity News reported, Portwood called off their wedding earlier this month when sources claimed he failed a lie detector test about cheating on his fiancée.

But insiders allege that she has yet to make “any final decisions” about the relationship, as they are “still living together” in their Indiana home.

Also on the episode, Maci Bookout learns “serious information” about her baby daddy Ryan Edwards.

“I got some information about Ryan and certain things he’s doing,” she said. “Stuff that isn’t very good at all. I’m not going to go into specifics. It’s scary stuff.”

When a producer asked her to explain the situation, she responded, “People are going to be like, ‘Oh he’s doing drugs!’ I did not know the severity of what is going on. Our number one priority is Bentley’s safety, but Ryan is his dad and I care about him.”

She added how her goal is to work with his parents to get Edwards “healthy and happy.”

“If something were to happen to Bentley I would never forgive myself ever,” she said. “I can’t sit back and watch it happen.”

As Breaking Celebrity News readers know, Edwards was accused of being high last season when he slurred his words and seemed out of it on an episode. Edwards denied the drug rumors.

Farrah Abraham tried to avoid drama by trying out hypnotherapy with her mom. She explained how her relationship with boyfriend Simon Saran has been “stressful” because they aren’t on the same page about marriage.
