Rod Stewart has vowed to get a vasectomy — after he fathers one more child. The legendary rocker, who already has seven children with five different women, says he would love to have a little girl with fiancée Penny Lancaster but would then call the time on becoming a father.

He said, “One more child and I am going to have to close the office. A girl would be nice.”

Rod, 61, who has a 10-month-old son with Penny, says he is pla-nning to marry the former model before they try for their second baby.

“We’re going to get married next summer — not sure where, but definitely next summer.”
