LONDON, March 11 (UPI) -- The wife of former Beatle Paul McCartney says being a mother is far more difficult than she had ever expected, the Daily Mail said Friday.
The newspaper also quoted sources saying in the next few weeks Heather Mills McCartney and her rocker husband will confirm she is expecting another baby.
McCartney gave birth to a girl 16 months ago and says she has been amazed at the effort motherhood takes.
"Motherhood is the hardest job in the world," said McCartney, 37. "All mothers should be paid a wage.
"Now, going to work feels like a holiday, even though I adore my baby."
If McCartney is pregnant, it will be the sixth child for her husband, 62. He has three from his marriage to his late wife Linda, plus an adopted daughter.
