Courtney Stodden is not holding back about her personal life.

The 21-year-old star, who famously married husband Doug Hutchinson, now 55, when she was only 16, is starring alongside her mother Krista Keller in the new Lifetime show, The Mother/Daughter Experiment: Celebrity Edition and revealed that she had relations with other men during her marriage.

Courtney admitted that when she was briefly separated from her husband, she was romantic with other men.

“That’s why we separated when I was 19. Because I was too young at the time," she said on Friday's episode. "I was going out — I was partying…”

When Natalie Nunn asked, "Hooking up with other men?" Courtney simply replied, "Of course!"

Doug, Courtney, and Krista.

The reality star has been very open about her relationship with her husband. On an earlier episode of the show, she famously admitted that she was "half a virgin" before she married Doug.

The show, however, is exposing the complicated relationship between Courtney and her mother, who gave permission for her daughter to marry Doug in 2011.

Now, as the two attempt to patch up their relationship, the show is exposing even more deep family secrets.
