Steven Tyler is "over the moon" that Liv Tyler is pregnant again.

The Aerosmith rocker is delighted his eldest daughter, who already has son Milo, nine, with ex-husband Royston Langdon, and her boyfriend Dave Gardner are expecting their first child.

The 66-year-old star told E! News: "I am over the moon that we are adding another member to our wolf pack."

He added: "Being a father and a grandfather is the greatest gift in life so far."

The 'Leftovers' beauty confirmed she is pregnant yesterday (30.09.14) after weeks of speculation.

The 37-year-old actress started dating Dave earlier this year after being introduced by their mutual friend Kate Moss and a friend recently said: "Dave's perfect for her."

The soccer agent, who is best friends with David Beckham, also already has a son, Grey, seven, with ex-wife Davinia Taylor.

Liv recently admitted she was "100 per cent planning" on having more children.

The 'Lord of the Rings' star said: "I hope I will have more children. I'm 100 per cent planning on it.

"If the stork could just drop it off on my roof, I'd be so happy - I'd have, like, 20."
