It's getting serious.
Steven Tyler playfully posed with pals Sheryl Crow and Melanie Griffith on the red carpet at the 24th Annual Elton John AIDS Foundation's Oscar Viewing Party on Feb. 28.
But when Steven, 67, was photographed walking inside, he was clutching another woman's hand.
The Mail On Sunday has identified the Aerosmith rocker's mystery date as 28-year-old Aimee Ann Preston.
Aside from being 39 years younger than the rock legend, Aimee is also his personal assistant.
They were first linked in 2014, although at the time, the Daily Mail characterized their romance as "early days" nothing they were "certainly having fun together."
According to the Mail on Sunday, Aimee recently posted pictures online of a new house she's believed to be sharing with Steven, who's 39 years her senior.
