Adult film actress Stormy Daniels will be among the guests on The Ray D'Arcy Show this weekend.
She is expected to discuss "her alleged affair with Donald Trump and the non-disclosure agreement that she signed in the run-up to the 2016 American Presidential Election."
Her "tell-all book", Full Disclosure, was published last month.
Ms Daniels said she is happy about her return to Ireland.
"After falling in love with Ireland on my previous visit, I could not be more excited to return," she said.
Host Ray D'Arcy says he is looking forward to "having a chat with one of the most talked-about women in the world at the moment" on Saturday at 9.50pm.
Also on the show, outspoken chef and restaurateur Richard Corrigan will be in studio to talk about hipster chefs, intimidation from vegans and why he thinks some British politicians are talking nonsense when it comes to Brexit.
Mark Little will chat about 'Fake News', the US political landscape, and launching his new News App.
24-year-old Muhammad and 83-year-old Austin, two housemates who live together in East Wall in Dublin and are taking part in RTE One's Home Rescue, will be on the show.
They will discuss moving in together, their unlikely friendship, and inter-railing together over the summer.
And newly-crowned Mr Universe, Wexford man Loughlan (Lock) Gannon, joins the line-up to celebrate last weekend's victory while also telling Ray how he overcame adversity in the form of both prostate and testicular cancer to compete and win the coveted Mr. Universe title.
