Aerosmith rocker Steven Tyler has confirmed reports his actress daughter Liv is expecting her second child.

Rumours suggesting The Lord of the Rings star and her boyfriend Dave Gardner were expecting their first child together surfaced last month (Sep14), and the Love in an Elevator hitmaker has now revealed he is thrilled about the baby news.

He tells Eonline.com, "I am over the moon that we are adding another member to our wolf pack. Being a father and a grandfather is the greatest gift in life so far."

Tyler is also mum to nine-year-old-son Milo William Langdon with ex-husband Royston Langdon.

The couple divorced in 2008.

This will be sports agent Gardner's third child - he has two kids from his marriage to English actress Davinia Taylor.
