When Liv Tyler and David Gardner welcomed their first child together back in February, grandpa Steven Tyler was there to snip the umbilical cord.

As the Leftovers actress revealed on Jimmy Kimmel Live! on Wednesday, Sailor had arrived six weeks earlier than planned, while her fiancé was traveling on business. Mia Tyler went to her sister’s side right away, but not before calling their father. Steven was in Nashville at the time, but caught a plane and “walked in just before everything happened,” said Liv. And with his long, painted fingernails, skull rings, and all, the Aerosmith lead singer cut his daughter’s umbilical cord.
