BoJo may need to work on his mojo.

British pol Boris Johnson — the UK bookies’ favorite to replace Theresa May as prime minister — got into a nasty beef early Friday with his much younger, live-in gal pal, according to reports from the UK.

Cops were called to the home Johnson shares with Carrie Symonds after neighbors reported a screaming match inside their plush flat in Camberwell, south London.

The Guardian reported that Symonds, 31, was heard telling the candidate for Tory leadership to “get off me” and “get out of my flat.”

She then was reportedly heard yelling that Johnson, nicknamed BoJo, had ruined a sofa by spilling red wine onto it.

“You just don’t care for anything because you’re spoiled. You have no care for money or anything,” she said.

Johnson, a pal of President Trump, was heard refusing to leave the home after telling Symonds to “get off my f–king laptop.”

The paper also reported that there was “banging and slapping” heard during the beef.

The altercation came hours after Johnson, 55, secured his place in the final round of voting to succeed May as party leader.

Two police cars and a van arrived shortly after midnight but left when told those inside the flat were OK.

“The caller was concerned for the welfare of a female neighbor. Police attended and spoke to all occupants of the address, who were all safe and well,” cops said in a statement.
