Sometimes love does mean having to say you're sorry.

Spencer Pratt has issued an apology to wife Heidi Montag, who recently filed for divorce after a year of marriage.

In an email to the Associated Press, Pratt, 27, says his behavior in the wake of their alleged breakup -- including his threat to release a sex tape -- was "outrageous and infantile."

Pratt confessed that he made "certain private issues public" and "horribly embarrass[ed] the one person who meant the world to me." He added that he wants to work on himself, and handle the split with dignity.

A source close to the reality stars recently told UsMagazine.com that the supposed divorce and sex tape are "all a PR stunt...They are still a couple."

Adds the insider: "They are not really breaking up. It's disgusting and vile, but Spencer will do anything to keep his fame...Whatever they do, though, will be together. He is doing nothing behind her back."
