Rod Stewart’s An Octodad

It’s a boy! On Thursday, rocker Rod Stewart, 66, and his wife Penny Lancaster, 39, have welcomed their second son together – and Rod’s eighth child in total.

After trying to conceive naturally with little success for two years, they decided to seek help from fertility experts. Baby Aiden was born on Wednesday, weighing in at 7 lbs, 12 oz.

“Mother and baby are healthy and blissfully happy,” a rep for the couple told PEOPLE this afternoon.

Penny and Rod have a five-year-old son, Alistair. Rod’s other children are Kimberley, 30, and Sean, 29, with his first wife Alana Hamilton. He also has Ruby, 23, by model Kelly Emberg and Renee, 18, and Liam, 16, by his second wife — model Rachel Hunter. His eldest daughter, Sarah, now 46, was born when Rod was only 19 and adopted at age 4. (They reunited several years ago…)
Aiden will be the final addition to the rock icon’s brood.

“One more and then we’re going to close the office,” he told British chat show GMTV in November.
