Aiden is the eighth child for the 66-year-old Stewart and marks his second child with Lancaster, who turns 40 in March - they also have a 5-year-old son together, Alastair.

"We were thrilled and delighted to be able to tell Alastair that he was going to be the big brother to a little baby, expected just before Mummy's 40th birthday," the couple said in a statement to Access Hollywood in August 2010 when they announced their latest pregnancy.
