Rod Stewart and his wife Penny Lancaster have welcomed a new baby boy into the world, the singer's record company said on Thursday.

The son, named Aiden, is the couple's second boy. They have another boy named Alastair Wallace who is five years old.

"Mother and baby are healthy and blissfully happy," Stewart's J Records label said. The baby was born on Wednesday.

Aiden is Stewart's eighth child. The 66-year-old British rocker has been married two previous times, along with having a string of long-term relationships with women, including model Kelly Emberg and actress Britt Eckland.

Stewart, whose hits include "Maggie May" and range from the late 1960s up to the 2000s, was previously married to models Alana Hamilton and Rachel Hunter before Lancaster, who turns 40 years-old in March.
