Michael Bublé says is it 'sucks' that he can't walk around in his underwear at home.

The singer admitted that his biggest fear is failing to produce good music.

However, he also confessed that his success across the world does have many downsides.

Now releasing his fifth album, Christmas, Michael is quickly becoming one of the most recognisable faces in the music industry.

The star doesn't like losing any of his privacy and he particularly hates his everyday life being caught on camera.

'I don't care how many records I've sold, you're only as good as your last album or your last show. But I'm also scared of more success,' he said in an interview with the British edition of Hello! magazine. 'It's getting bigger and bigger and I worry about losing my privacy. It seems photographers are lurking everywhere, and when I'm at home at night I close the drapes. I'm not like a normal guy who can walk around in his undies and that sucks.'
