Teen Mom OG star Amber Portwood and boyfriend Andrew Glennon are expecting their first child together, which will be her second, she confirmed Friday.

The two are "excited about their future together," a source told E! News exclusively. "He is with her in Indiana and the relationship is going strong. He has been filming with her."

Amber tweeted, "Thank you everyone for all the kind words. I'm very excited for my future with Andrew and our little family we are starting together! Love"

She and ex-boyfriend Gary Shirley are parents to daughter, Leah, who will turn 9 this month.

Portwood, 27, and Glennon met earlier this year while she was filming Marriage Boot Camp with ex-fiancé Matt Baier. He and the reality star had split mid-production. Portwood and Glennon made their red carpet debut as a couple this past August at the 2017 MTV VMAs.
