Is Amber Portwood moving too fast with fiance Matthew Baier?

Amber Portwood Spotted With Gary Shirley's New Baby

According to a sneak peek at tonight's new episode of Teen Mom OG, Portwood's cousin, Krystal, feels the reality star may have jumped the gun in regard to her engagement, which aired on last week's episode.

"You want to hear my concern?" Krystal asks Portwood in the sneak peek, provided by OK! Magazine on Monday. "My concern is that you may be moving fast. It's just weird to me, okay? It's different. It's weird."

Amber Portwood Defends Her Engagement To 43-Year-Old Matthew Baier

While Portwood and Baier have appeared fairly solid on newly airing episodes of Teen Mom OG, Krystal claims Portwood recently came to her, admitting the age gap between them is a bit of a worry. In addition to that, Krystal believes their relationship was plagued with ups and downs prior to their engagement.

"The last time I talked to her, there was concerns about the age," Krystal explained. "And then the next talk, it's, 'We got puppies,' and I was like, 'What in the f**k changed within like a week?'"

Still, Portwood claims what she and Baier have is legit, and any concerns she previously came across are no longer relevant.

"Ever since we've been around each other and just hanging out, it's not as apparent," Portwood said.
