AEROSMITH Singer STEVEN TYLER Becomes Grandfather

According to E! Online, AEROSMITH frontman Steven Tyler officially became a rock 'n' roll relic Tuesday (Dec. 14) as daughter Liv Tyler gave birth to a baby boy.

It's the first child for the 27-year-old "Lord of the Rings" star and her British rocker hubby, Royston Langdon, 32 — and the first grandkid for the 54-year-old AEROSMITH screecher.

People reports the baby made his grand entrance at 4:11 a.m. and weighed 8 pounds. Us Weekly reports that the birth occurred at New York-Prebysterian Hospital, with both Langdon and Tyler's famous father in attendance.
