Rod Stewart and Penny Lancaster welcome second child

Rod Stewart and Penny Lancaster welcomed their second child together, a boy named Aiden, on Wednesday, Feb. 16. He weighed in at 7 lbs., 12 oz. A rep for the couple tells People, "Mother and baby are healthy and blissfully happy."

Aiden is the eighth child for Stewart, 66 (forever young!), and he comes as an early birthday gift for Lancaster, who turns 40 in March. Aiden joins big brother, Alastair Wallace, who is 5. In August, the couple said, "We were thrilled and delighted to be able to tell Alastair that he was going to be a big brother."

The singer and model married on June 16, 2007, on a yacht in the Italianport of Portofino.  Alastair was born Nov. 27, 2005, in London. Stewart's first child, Sarah Thubron Streeter with Susannah Boffey, was born in 1964.
