NEWS: Liv Tyler Gives Birth To Second Son

The proud grandpa posted a pic to Facebook of himself and daughters Liv and Mia Tyler from Liv's hospital room.

"When I got the call that Liv was going into labor, after crying like a baby myself, I immediately dropped everything and went to the airport to get on the next available flight," Tyler wrote on his Facebook page.

"When I landed I kept calling my daughter Mia Tyler who was already helping Liv and she kept giving me minute by minute updates, 'HURRY THE BABY IS COMING!'"

Thankfully, the Aerosmith frontman didn't have to miss a thing, as he made it to the hospital just in time.

"I made it RIGHT in time before my second grandson entered this world," Tyler wrote. "It was another (God wink) moment of a lifetime for me."
