Texting while driving caused Hollywood plastic surgeon Dr. Frank Ryan's fatal accident on the Pacific Coast Highway, his ex-girlfriend told People magazine.
"He lived up in Malibu on a tiny street and he was texting while driving, and he accidentally went over the cliff," Charmaine Blake said.
She said Ryan's family was told by investigators that his texting contributed to his death.
California Highway Patrol confirmed to People that Ryan, 50, was texting before the crash, but would not say it caused the accident.
"It is one of the elements that we are investigating," CHP Officer Steven Reid said.
Minutes before his crash, Ryan had Tweeted: "After 25 years of driving by, I finally hiked to the top of the giant sand dune on the pch west of Malibu. Much harder than it looks! Whew! ... Border collie jill surveying the view from atop the sand dune."
He also Tweeted a photo of his dog on the dune.
Emergency responders attempted to remove him from vehicle, but were unsuccessful. He was pronounced dead at the scene. His dog Jill was thrown from the vehicle and found in the ocean. She suffered serious injuries to her head, paw and eye and was later released to a member of Dr. Ryan's ranch staff, TMZ reported..
Ryan was a staple in Hollywood, working on countless celebrities including Janice Dickinson, Adrianne Curry, Shauna Sand and Gene Simmons.
But it was his work with MTV reality star Montag that earned him notoriety; he completely (and publicly) transformed the troubled celebrity's looks. Performing 10 procedures in one day, Ryan gave Montag a mini brow lift, Botox, a nose job, a "back scoop," liposuction and an ear pinning, among other alterations.
