spenceheidinote460.jpgSpencer Pratt is saying sorry to his wife, Heidi Montag, for being "outrageous and infantile" in regards to his threats about releasing a sex tape.

Pratt, 27, admits that he has made "certain private issues public" and "horribly embarassed the one person who meant the world to me," according to an email he sent to the Associated Press.

Montag's other half adds that he wants to handle their alleged split "with dignity." Pratt also tweeted, "I need to apologize to Heidi and my 11.5 fans. I'm an epic douche - and you deserve better."

A source close to the couple tells X17online exclusively:

    "Heidi and Spencer have made a fortune off fooling the public. They're running out of fake stories to keep themselves in the press. Heidi has talked about bringing up the fact that she wants to have a baby, but they want to let this sex tape story play out for awhile. The stories of them splitting are BS, and I think the public knows that already."


A rep for Heidi and Spencer have not returned requests for comment.
