Lord Alan Sugar and Karren Brady have ''lots of dinners and chats'' even when they're not filming 'The Apprentice'.
The 47-year-old sporting executive has been the business magnate's assistant on the show since 2010 but has admitted their friendship extends further than on screen.
Speaking to OK! magazine, she said: ''We have a lot of dinners and chats. Alan and I are both in the House Of Lords, so we see each other a lot there. He's incredibly witty and there's no end to the amount of laughs we have.''
The brunette beauty dishes out advice to contestants while they're taking part in tasks on the show but is adamant no one tries to flirt with her to get the upper hand on the others.
Karren - who is married to football manager Paul Peschisolido, with whom she has two children daughter Sophia and son Paolo - she explained: ''I don't think I have the sort of aura that says come and flirt with me!
''I think that would work about as well as trying to flirt with Lord Sugar! I think Alan and I are the least flirtable people on TV!''
Meanwhile, Karren will appear back on screens next month as 'The Apprentice' returns for another series and she's managed to lose weight without slaving away in a gym.
She said: ''I stopped eating crap! I've been eating less and exercising more. It always happens when I'm on the show because we're running around, so I just kept it up. I don't go to the gym but I walk a lot. My weight has never been the focus of my existence. You won't ever find me on a treadmill!''
