Heather: Being a mum is hardest job

There are rumours that she is expecting her second child.

But given Heather Mills McCartney's latest comments about motherhood, she may not exactly be looking forward to it.

The wife of Sir Paul McCartney - who, thanks to his £ 800million fortune, could employ an army of nannies - has complained that being a mother is almost too difficult to bear.

'Motherhood is the hardest job in the world - all mothers should be paid a wage,' said the 37-year-old former model, who presented Sir Paul, 62, with a daughter, Bea, 16 months ago.

'Now, going to work feels like a holiday, even though I adore my baby.

'Whenever I speak to my friends they say the longer you're at home the more confidence you lose. It's absolutely true - talk about multi-tasking!

'I've just started to get a babysitter to give me a bit more time but usually my baby is climbing on my lap deleting my e-mails or cc'ing private ones to inappropriate people.'

Her comments come in an interview with the magazine Hello! in which she reveals she has no desire to be a full-time mother, preferring to concentrate on her broadcasting ambitions.

'I'd love my own TV show,' she says. 'Presenting is what I did for years before meeting Paul and I gave it up as he wanted me to be with him when he travelled.

'I loved presenting Larry King's talk show in the States and look forward to doing more in the future.'

Although she says she is struggling to get time away from her daughter, she admits to having time to exercise five times a week, with a bevy of personal trainers.

'I do five days in a row, one hour a day, with weekends off to allow my muscle tissue to recover,' she says. 'As we travel all the time, how and with whom I work out varies. Now, my biggest treat is to work with a personal trainer where possible and that's Richard in London, Chad in LA and Claus in New York.'
