Stella brings Macca joy with baby Linda

Stella McCartney, the daughter of former Beatle Sir Paul, has given birth to a baby girl.

And the fashion designer has named her second child after her mother. The 35-year-old fashion designer gave birth to Bailey Linda Olwyn Willis.

The baby's arrival is welcome news for Sir Paul, but will be seen as a slap in the face for his second wife Heather Mills, whom he is divorcing and Stella is said to loathe.

He married Heather only four years after his first wife Linda died from breast cancer in 1998 and his children were said to have been furious about the relationship. Stella and her husband of three years, former magazine publisher Alasdhair Willis, 36, already have a son, Miller, who will be two in February.

Bailey weighed in at 7lb 14oz on Friday. He is the fourth grandchild for Sir Paul.

His 37-year-old photographer daughter Mary has two sons, Arthur, seven, and four-yearold Elliot. They are both older than the former Beatle's youngest child, three-year-old Beatrice Milly, his daughter with Heather.

The latest addition to the McCartney clan was born in the same week Ms Mills represented herself in court in applications to keep Sir Paul out of her home and to gain access to his. She is said to want to reduce her mounting legal bills.

But she is thought to have retained the services of London law firm Mishcon de Reya in the main divorce battle over money and custody of Beatrice.

Ms Mills's final legal bill could be as high as £1 million, but she is likely to receive at least £20million - and as much as £100 million - in the battle for Sir Paul's estimated fortune of £825million.
