McCartney, Mills Expecting a Baby
NEW YORK (Reuters) – Former Beatle Paul McCartney, 60, and his second wife, Heather Mills, said on Wednesday that the couple are expecting a baby later this year.
“We are delighted with this happy news,” the couple said in a statement.
McCartney and Mills married in June 2002. McCartney has three children from his 29-year marriage to Linda McCartney, who died of breast cancer in 1998. He also adopted Linda’s child from an earlier marriage.
Mills, a former model who lost her left leg below the knee in an accident, met McCartney at a charity event three years ago.
McCartney helped revolutionize popular music in the 1960s as a member of the Beatles. After they split in 1970, he continued as a solo artist and with the band Wings, which he formed with Linda.
