Spencer Pratt, best known for his bad boy role on the MTV reality show “The Hills,” has issued a long public apology to his wife, Heidi Montag, People magazine reports.

In an interview with the magazine, Pratt addressed the woman he is divorcing and said he will do “intense soul-searching” and will pursue "appropriate avenues for my issues," the story reports.

"Divorce can be a trying, draining, and emotionally devastating experience for all involved," Pratt, 27, is quoted as telling the magazine. "Despite these hardships, most individuals manage to conduct themselves with dignity and maturity. I did not–I failed spectacularly."

Pratt has threatened to release a sex tape involving Montag, has Twittered negatively about her and has pursued her in Costa Rica, the story points out.
