She continued: "The real wife of the 57 year-old actor is EASILY AT LEAST 50. But this f*** wants to be tv married to a 38 year-old - TOPS
"This is a FIRST marriage, btw. Not a re-wife. Which would make a little more sense. F*** HOLLYWOOD."
She wouldn't reveal the age of the male actor, but Denbo replied to several of her followers who pleaded for her to name and shame him, but she would only spill that he was an "American treasure".
Denbo is far from being the first actress to have been overlooked for a suitable role because of her age.
American Horror Story actress Jessica Lange, 68, previously said: "At a certain age women are no longer considered a viable or a valuable part of the community - even if that's when they may feel like they're at the top of their game."
Hollywood legend Susan Sarandon, 70, agreed with Lange and said there were many tragic stories of women in the industry.
She said: "All of those gals who had these amazing parts found themselves high and dry later when they were older because there weren't that many people who were writing them.
"There are so many tragic stories of women who were so beautiful and couldn't figure out a way to age within the system."
