Courtney Stodden and Doug Hutchison expecting first child

Reality star Courtney Stodden and actor Doug Hutchison are expecting their first child after five years of marriage.

The reality star told ET, "I feel happy about it but extremely overwhelmed."

"I'm going through a lot at the moment. This wasn't a planned pregnancy," the 21-year-old explained. "But life happens."

Stodden and Hutchison got married in 2011, setting off a media firestorm when it was revealed that Stodden was just 16 years old; Hutchison was 51. The two met when Stodden sent Hutchison an e-mail through his website, starting a correspondence. With Stodden's mother's approval, the couple got married in Las Vegas. It was Hutchison's third marriage.

Hutchison and Stodden sat for a "Nightline" special that year about their May-December romance. The then-teenager also released viral music videos on YouTube, and the couple released many provocative photos on social media. The two have remained at least on the fringes of the limelight since then; they also split for several months in 2013 before reconciling.

There's never an ordinary day for the Stodden-Hutchison family, it seems. Stodden and her mother, Krista Keller, are now on Lifetime's "The Mother/Daughter Experiment: Celebrity Edition." Keller recently admitted on the show that she told Hutchison she was in love with him.
