Something’s fishy in this new sneak-peek clip from Teen Mom OG, and it’s not Amber Portwood’s Indian curry that she dines on with her fiancé, Matt Baier.

After expressing how excited she is to spend time with her daughter, Leah, later that day, Amber receives a call from her ex, Leah’s dad Gary Shirley, while out to lunch. Gary tells Amber that Leah doesn’t want to come over to her house.

“I’m so f–king confused right now,” a hurt Amber tells her fiancé after getting off the phone.

“I’ve never seen her act like that,” Matt replies.

But Amber smells a rat. She thinks Leah might be being influenced by her father, who took care of Leah while Amber served a 17-month prison sentence.

“Something’s going on,” she said. “I hope he’s not saying s–t to her. I think he’s getting scared because I said that s–t about custody. If I ever find out he’s saying s–t to her, it’s on.”

Watch the clip to see what happens. Teen Mom OG premieres Monday, January 4, at 10 p.m. EST on MTV.
