Charlie Sheen and fiancé Brooke Mueller are planning to exchange vows in a ceremony on Friday evening, according to the latest reports.

Friends of the soon-to-be Mrs Sheen are also claiming that the real estate investor is pregnant, the pair having been “busy working on having a baby" for a couple of months.

With any luck Denise Richards' reaction to her ex-husband's nuptials will be captured for posterity on her new reality show, Denise Richards: It's Complicated.

"They had to tell Denise when it was, because they wanted the girls to come, but she doesn't know where it'll be," a source tells the NY Daily News' Rush & Molloy column.

"Who knows? She may even crash the event with a camera crew."

We’d watch!
