Drew Peterson says he's engaged to be married

Drew Peterson's publicist says the former police sergeant is engaged to be married again.

Glenn Selig says the 54-year-old Peterson proposed within the last week after dating the woman for about four months.

He says the woman is 23 -- the same age as Stacy Peterson when she disappeared in October 2007. Selig wouldn't provide any details about the woman and Peterson wouldn't comment.

The engagement was first reported in a news release Wednesday morning by Derek Armstrong, the author of a book about Peterson.

Peterson claims his wife left him for another man. He has met with an attorney to discuss filing for divorce on grounds of abandonment. But he and Stacy Peterson are still legally married.
