Denise Richards denies reports to `Roast` Charlie Sheen

London: Actress Denise Richards is baffled by reports that she is set to poke fun at ex-husband Charlie Sheen when he is honoured at the TV series `Comedy Central Roast`.

The show, which sees top funnymen crack jokes at the star`s expense will see Charlie Sheen as the guest and is due to take place in September, reported Daily Star. Richards insisted she`s not been approached to `Roast` her embattled former husband. "I just heard the news I`m roasting Charlie? First I`m hearing this, Is that appropriate for the mother of his children to do that? Good, Bad? (sic)" Richards wrote on Twitter. But the producers are reportedly in negotiations with the former `Bond` girl, who has two daughters with Sheen, to make an appearance on it. PTI
