Disgraced Prince Andrew visited his queen mum under the cloak of darkness last week — in a secret bid to plot a potential comeback to public royal life, a report says.

The British royal, 60 — who has been tied to late pedophile Jeffrey Epstein and accused socialite pal Ghislaine Maxwell — sneaked into Windsor Palace late Tuesday for the hush-hush tet-a-tet with his mother, sources told Britain’s The Sun.

“This looked like a deliberate attempt not to be seen,’’ an insider told the outlet.

But while Queen Elizabeth may be sympathetic to her youngest son’s plight, his brother, Prince Charles, and nephew Prince William are “united’’ in their stance that he should not be returned to any public role, sources added to the Mirror of Britain.

There is “zero chance’’ he would be allowed back to his royal work, palace sources said — with the insider adding, “There is no way of him ever returning to front-line duties, and he will remain very much on the outside.

“Whatever [Andrew] may think his future looks like, he should be under no illusion that view is not shared by the people who actually make the decisions within the family,’’ the source said.

The divorced prince is accused of having sex with then-17-year-old Epstein sex slave Virginia Giuffre in the early 2000s, when he was in his 40s, with the help of Maxwell.

Epstein was being held on sex-trafficking charges involving scores of young women in a Manhattan federal jail when he committed suicide in August 2019.

Maxwell is currently jailed on sex-trafficking and other charges involving her time with Epstein.

Andrew has vehemently denied any allegation of wrongdoing, as has Maxwell.
