Must-See Celebrity Instagram Posts of the Week

Portwood expresses her concerns with a producer before speaking.

Amber Portwood was clearly very cautious when it came to talking about her arrest while filming the upcoming "Teen Mom OG" reunion.

Though it doesn't air until Monday, MTV dropped a preview clip on Thursday, showing the reality TV star and Dr. Drew Pinksy sitting down together for her solo interview.

ICYMI: the season finale ended with Portwood's domestic battery arrest from July 5. Now ex-boyfriend and father to her child, Andrew Glennon, contacted cops claiming she hit him with a shoe while he was holding their child. She also allegedly wielded a machete during the incident.

"Let's talk about how you've been doing since the arrest," Dr. Drew begins. "Why don't you tell me the story, what happened?"

She's immediately standoffish. "I can't really," she begins, as he tells her, "to the extent that you're able."

Looking off camera, she tells a producer, "I really need some assurance." The woman's response: "We don't want you to say anything you can't say."

"You're going to talk to my lawyers and just like, please figure something out," Portwood tells her. "I want to get my side of the story out, however..."

That's where the clip ends. What a tease!

In last week's season finale, MTV addressed the arrest with a slate reading, "On the night of July 4th, Andrew sent a text message to 911." An officer's voice was then heard saying, "I received a text message from someone that their life and their son's life is in danger," as an image of Amber's booking photo was shown.

In the episode, MTV caught up with Amber's ex, and father of her daughter Leah, Gary Shirley and his wife Kristina after the news broke. "I wish we could just wake up and say it was a dream," Kristina said.

"You know, if anything is true, from what I heard, there need to be some sort of repercussions for something. He's saying one thing. She's saying one thing. And a hit's a hit. Whether you do it with a flip flop or a hammer," Gary said to his wife.

Gary then turned the conversation to the effects on their family, specifically 10-year-old daughter Leah. "I mean this has an impact on all of us. She didn't just affect her own self and her own family, it trickles down to us too," he said.

"It's heartbreaking. I know it's flipped the world upside down of everyone that's involved. How do we continue to co-parent with, you know, the legal issues involved and Leah's emotions? And I know that you're taking it pretty rough too," Kristina told her husband.

"I mean, ultimately, Leah is almost 11. She knows a lot of what's going on," Kristina added. "I think the only thing she's said to me though was, 'If mommy goes back to prison, what will happen to James? Will James be taken away from me as well?' And I don't have those answers, I don't know how to answer her. She deserves to be a kid, and these are adult situations."

The two-part "Teen Mom OG" reunion airs Monday and Tuesday on MTV.
