Charlie Sheen claims Donald Trump once tried to impress him with an improvised - and worthless - wedding gift.

The actor said Trump came up to him at a restaurant where he was having dinner with his then-wife Brooke Mueller and offered him fake jewelry as a present.

'I noticed Donald staring at my watch. He says, "I want to give you an early wedding gift from me and Melania,"' Sheen said during an appearance on the Graham Norton Show.

During an appearance on the 'Graham Norton Show,' Charlie Sheen said Donald Trump once gifted him cuff links made out of cheap material

'He says, "These are platinum diamond Harry Winston," and he pulls off his cuff links and he gives them to me,' Sheen said of Trump

Sheen said an appraiser deemed the cuff links to be made out of 'cheap pewter and bad zirconias'

Trump's wife, Sheen added, was 'very sweet and very pretty but kinda just sits there.'

'Anywho, so he says, "These are platinum diamond Harry Winston," and he pulls off his cuff links and he gives them to me.'

Months later, when Sheen had the jewelry appraised, he said an expert found the cuff links to be utterly worthless.

'[The appraiser] took the loupe, spent about four seconds and kind of recoiled from it — much like people do from Trump,' Sheen said.

'She says, "In their finest moment, this is cheap pewter and bad zirconias." And they're stamped "Trump."'

Donald Trump was labeled a 'charlatan' by Charlie Sheen in a recent television interview. Pictured speaking in North Carolina last week

'I just thought, what does this really say about the man that he said, "Here's a great wedding gift," and it's just a bag of dog s**t?'

Sheen, who has been on a recent publicity blitz advocating for the use of condoms in light of his highly-publicized HIV infection, is a vocal opponent of Trump, even though he once petitioned to be the presumptive Republican nominee's running mate.

He branded him a 'charlatan' in the interview with Norton.
