Alec Baldwin made an explosive confession in his new memoir, Nevertheless.

And now famed producer Dana Brunetti, 43, is speaking out against the claim that the 59-year-old actor (who was 47 at the time) didn't know co-star Nikki Reed was 'seventeen' while filming R-rated drama Mini's First Time in 2006.

'My first indie film was Mini's starring @AlecBaldwin who knew @NikkiReed_I_Am was 16 (not 17) and he didn't mind,' Brunetti began his twitter rant.

It's not true! Famed producer Dana Brunetti, 43, is speaking out against Alec Baldwin's claim he didn't know co-star Nikki Reed was '17' while filming R-rated drama Mini's First Time in 2006

Alec claimed in the new book that he did not know Nikki was underage when they filmed sex scenes for the movie and that he 'flipped out' at producers when he learned the truth.

But Brunetti says that's not true and goes into a long-winded explanation taking up 11 tweets.

The House of Cards producer goes on to explain that Alec knew before Nikki was cast: 'in fact @NikkiReed_I_Am was 1 of 4 actresses "AlecBaldwin had approved and her being the only 1 of those 4 repped by HIS own agency CAA.'

He claims that if Alec yelled at the producer, it wasn't him.

'My first indie film was Mini's starring @AlecBaldwin who knew @NikkiReed_I_Am was 16 (not 17) and he didn't mind,' Brunetti began his twitter rant

In a 11-tweet rant, the producer claims Alec knew Nikki was underage before they started filming and never 'yelled' at any of the producers

'The only time "AlecBaldwin ever yelled at me was on the phone and it was about one of the producers who worked with the financier.'

The two-time Oscar-nominated producer goes on to explain that the film's director Nick Guthe liked the idea because they wouldn't be 'pressured into shooting scenes with nudity.'

Fabrication? Brunetti says Alec has been 'impersonating' Trump for too long and was doing a bit of 'method acting' when writing his new book

Trying to give Alec the benefit of the doubt, he jokingly asserts the actor might be 'impersonating Trump a lot, so maybe there was a bit of method acting when writing his book?'

He also asserts he has confirmation from three other members of the cast and crew backing him up and says the real issue in the book is that he says Alec yelled at producers.

'If @AlecBaldwin had simply said in his book he didn't know @NikkiReed_I_Am's age, I would let it go. However to say that when he found out after filming he yelled at the producers (I being 1 on the film) makes it out to seem we did wrong.'

Brunetti, who is President of Kevin Spacey's production company, brought the A-lister into the mix.

He finished: 'UNLESS @AlecBaldwin saw @KevinSpacey some event after and yelled at him?? Though that would be wrong too, because again, Alec knew.'

'I flipped out': Alec was 47 when he filmed the scenes with a 16-year-old Reed for the film

Mini's First Time is an indie film produced by Kevin Spacey's production company Trigger Street Productions and features Alec as a married man who has a torrid affair with his step-daughter (Reed).

Vanity Fair did a profile on Brunetti in 2016, calling him the most hated executive in Hollywood, as he's young, successful, handsome -- and owns three Ferraris.

His successful box office hit Fifty Shades of Grey made $564 million at the box office.
