Just weeks after Amber Portwood announced that she and her new boyfriend, Andrew Glennon, are expecting a child together next year, the "Teen Mom OG" star's ex-fiance, Matt Baier, has announced some big news of his own. According to a new report, Baier has moved on from his romance with Portwood with another woman, who he reportedly married in Las Vegas just a short while ago.

The Ashley's Reality Roundup was first to share news of Matt Baier's wedding and did so on November 28. According to the outlet, a marriage certificate was filed for Baier and his wife, a 35-year-old woman named Jennifer, in Clark County, Nevada on Tuesday, just one day after the couple applied for their marriage license.

Jennifer reportedly works in Las Vegas as a waitress and is said to be a single mother. As for the nature of her relationship with Matt Baier, who has been married three times, The Ashley wasn't sure when their romance began but noted that they have been living at the same address for at least a few months.

Did Amber Portwood know that Matt Baier was getting married?

“[Amber Portwood] is not aware that he got married,” a source explained to The Ashley. According to the report, Portwood was not made aware of Baier and Jennifer's wedding and doesn't appear to have had any contact with her former fiance in recent months. Instead, she's focused on her recent baby news as she continues to juggle her long-distance relationship with Andrew Glennon.

While filming "Marriage Boot Camp: Reality Stars" with Matt Baier, Amber Portwood met and fell in love with Andrew Glennon and began dating him a short time later. Since then, Portwood and Glennon have been traveling back and forth between her home in Indiana and his home in Malibu, California.

While Portwood and Glennon began dating in August, they wasted no time heating up their relationship and after a romantic vacation in Hawaii in September, Portwood was confirmed to be pregnant with her second child, the first child for her boyfriend. No word yet on the gender or due date of Portwood's new baby.
