Professor Brian Cox has won thousands of female fans since he popped up on TV presenting shows like BBC2's Stargazing Live - but the TV scientist is a very private person.
When Brian, 43, married wife Gia in a secret ceremony in Minnesota in 2004, even his parents didn't get an invite.
'It does seem quite eccentric in hindsight, doesn't it?' says Brian.
'Am I selfish? That's probably fair. I'm self-contained. I can amuse myself - sit and play the piano, read, write.
'But Gia is as well. She's learning Egyptian at the moment.'
And Brian - who has a PhD in physics and holds a professorship at the University Of Manchester - is still getting used to being famous.
His self-contained personality makes it hard for him to chat to fans.
'The other day, a woman came to the door and said: "You're on the telly, aren't you?' I said: "No I'm not. Goodbye." And shut the door,' Brian tells Weekend.
'Afterwards, I thought: "I probably didn't get away with that."
'I seem to be quite well-known, which is a surprise for someone who makes science programmes.'
