"It was totally unexpected, but she is really excited," a source close to Portwood, 27, told Radar. "She's been feeling really sick lately, but her spirits are good."
Portwood, who is currently two months pregnant, told her loved ones. "She told her friends and family about the pregnancy a few weeks ago," the insider said. "They all had a good reaction."
Radar broke the news earlier today that Portwood may be expecting a child with Glennon. "There are rumors around town that Amber is pregnant," a source told Radar.
Portwood sparked pregnancy rumors when she went quiet over social media in late summer. The mother of Leah, 8, with ex-fiancé Gary Shirley often posted sexy full-body shots and live videos on Instagram.
The MTV star checked in with concerned fans in October by tweeting, "Hi loves! I know I've been MIA however I just want to say I'm happier than ever and focusing on family."
Portwood began dating producer Glennon, 33, while filming Marriage Boot Camp with her ex-fiancé Matt Baier.
