Leave your answers in the comments.
Reports are in that Gwen Stefani gave birth to a baby boy just after 1pm on Friday. Congrats to the newest member of Club Motherhood. The couple has considered the name Kingston, King for short.
Rod's delightful progeny have yet to spawn...too busy hanging out with La Hilton and picking up her scraps, lol.

Paul =4k, 3gk
Mick = 7k, ?gk

Kingy King...that's got to be the hottest boy name going these days.
No Doubt ;-)
Shit, that is SO not what grandpas are supposed to look like.
Damn my grandpa was not that hot.
Ok..Tyler has 4 kids, Liv, Mia, Chelsea and Taj. Liv has a 1 1/2 yr old son, Milo giving Steven 1 grandchild.
Rod Stewart has ?? children (didn't he just have another one?) but no grandchildren.
Mick has 2 daughters (that we know of).
Paul has 2 with Linda, 1 with the one legged woman and another one somewhere, so surely one of them is knocked up by now..heee!
Paul McCartney has one stepdaughter, Heather, from his marriage to Linda, two bio daughters with Linda, Mary and Stella, and one son with Linda, named James. He also has a 2-year old daughter with Heather Mills (named Beatrice, or am I completely off here...). I know he has at least one grandchild from one of his older daughters.
