Appearing to take her former spouse's cutting words on the chin, the 44-year-old actress decided to take the moral high ground and simply wish the former Two And A Half Men star a 'happy Father's Day' on behalf of their two daughters, Sam, 11, and Lola, 10.
And while she went for the classy approach when it came to responding to her ex's somewhat bizarre slurs, Denise admitted her girls were 'disappointed' they couldn't spend the special day with their dad.
Two can play at that game: Denise Richards has responded to her ex-husband Charlie Sheen's erratic rant, in which he branded her a 'washed-up piglet shame pile'
In a series of Twitter posts, Denise wrote: 'Happy Dad's Day! @charliesheen have a great trip in Mexico! Kids were disappointed u weren't here for it- Hey we'll celebrate when u r back!
'And Happy Fathers Day to all the dads including my own dad Irv! Best dad ever & an amazing Grandpa!'
