Crazy, but Steven Tyler is a newly minted grandfather.
The Aerosmith frontman officially became a rock 'n' roll relic Tuesday 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.
News of the birth was confirmed by Liv Tyler's publicist, Stephen Huvane, who said the couple was "thrilled."
According to People, the tyke is named Milo, and he made his grand entrance at 4:11 a.m., weighing 8 pounds. Us Weekly reports that the birth occurred at New York-Prebysterian Hospital, with both Langdon and Tyler's famous father in attendance.
According to People, Tyler had a quick labor and felt "terrific" afterward. The magazine quotes a source close to the actress saying, "My baby is so handsome I can't stand it." The boy apparently inherited some genes from the Tyler side. "He also has full lips," the source said.
Back in June, when she first announced she was with child back in June, Tyler told People, "Roy and I are both overjoyed and look forward to the arrival of our child."
The couple wed in a private Caribbean ceremony in March 2003, after a two-year engagement.
Tyler, offspring of Steven Tyler and model Bebe Buell, got her big break starring in Aerosmith's 1994 video "Crazy."
She has since moved out from under her father's shadow, first as a successful model and then going on to star in close to 20 movies over the last decade, including That Thing You Do! and Armageddon. But she is best known as the lovesick Arwen in the Lord of the Rings trilogy.
Her next movie, Lonesome Jim, helmed by Steve Buscemi and costarring Casey Affleck, is slated to make its premiere at the Sundance Film Festival next month.
Leeds-born Langdon and brother Anthony formed Spacehog in 1994, and the sibs scored a mid-'90s radio hit with the single "In the Meantime."
The 'Hog went belly up last year and Royston Langdon formed a new band, the Quick. The three-piece outfit has been playing gigs around New York, but is apparently on hiatus while the new daddy tends to diaper duty.
