Newcastle-born TV presenter Ant, of Ant and Dec fame, has he admitted voted Conservative in the last general election.
Anthony McPartlin, who grew up on a council estate in Newcastle - but now lives in west London and has hosted a string of hit ITV shows with his presenting partner Declan Donnelly, made the comments in an interview with Guardian Weekend magazine.
The 37-year-old said he had always voted Labour until the 2010 general election, when he voted Tory.
"Which would make a lot of my family up north very angry," he said.
"I haven't actually told them, so when they read this they'll go, 'What?' But they certainly couldn't give an argument for Labour for me at the moment - not a valid one.
"Then again, I'd struggle to give an argument for voting Conservative at the moment."
In the interview, the Britain's Got Talent hosts also admitted taking drugs.
"Years ago (we took drugs), yeah," McPartlin said.
"But we're not really druggy people, that's the thing.
"I think you either go into that crowd as a kid or you don't, and we didn't. We found the love of alcohol very early on and we stayed with it."
Donnelly, also 37, added: "There's a real pub culture where we're from in Newcastle, so we're just more boozy people."
The pair are back on screens tonight with a new edition of Saturday Night Takeaway on ITV.
The variety show was caught up in the premium-rate phone-in scandal in 2007, after it was revealed that viewers were calling premium-rate numbers to win prizes that had already been given away.
The pair were not complicit in the scandal but admitted they thought it could cost them their careers.
"That was just the worst, worst period ever," Donnelly said.
