Rod Stewart became a father for the eighth time on Thursday after his wife Penny Lancaster gave birth to their son Aiden.

The 66-year-old rock star and his wife said they were "proud and thrilled" to announce the "long awaited arrival.” Aiden joins big brother Alastair, who is five years old.

Lancaster and Stewart, who have been together for more than a decade, revealed they were expecting last summer after intensive IVF treatment.

"I couldn’t believe it. I burst into tears. I called Rod when I was still sobbing," Lancaster said.
