Mel B Opens Up About Decision to Enter Rehab

"No, I'm not an alcoholic. No, I'm not a sex addict. I was with the same person for 10 years and it was quite a turmoil, very intense," Mel B says about the PTSD that stemmed from her past marriage.

Mel B got candid about her decision to check into a treatment program for post-traumatic stress disorder on Wednesday's The Ellen DeGeneres Show.

Guest host Lea Michele began the segment by stating that Mel B had recently made headlines after announcing that she planned to enter a rehab facility. The Spice Girls singer told The Sun on Saturday that working on her new book Brutally Honest forced her to relive what she has described as an "emotionally abusive" relationship to her ex-husband Stephen Belafonte. "I have made the decision to go into a proper therapy program in the next few weeks, but it has to be in the U.K. because I am very, very British and I know that will work best for me," she said.

"I've been in therapy since my father got diagnosed with cancer nine years ago," added Mel B. "But then my therapy changed a little bit because I was in a very intense relationship."

The singer said that she details her past marriage to Belafonte in the book. "I do address a lot of those issues," she said. "No, I'm not an alcoholic. No, I'm not a sex addict. You know, I was with the same person for 10 years and it was quite a turmoil, very intense. That's all I can say about it. I'd like to say a lot more, but let's keep it PC. But yeah, I address a lot of those issues and I did kind of have to ease my pain."

Added Mel B, "I suffer a lot from PTSD."
