Stella welcomed Bailey Linda Olwyn Willis, born on Dec. 8 in London, weighing 7 lbs., 14 oz.
This is the second child for the couple. They have one son, Miller, who turns 2 on Feb. 25.
Bailey is the fourth grandchild for rocker, Paul McCartney.
We wish Stella and her husband the very best. Having 2 children under two will not be easy, but I am sure she will do well.
