Aerosmith rocker Steven Tyler, 67, has moved in with his much younger personal assistant, Aimee Ann Preston, 28, in LA and Nashville, Tenn., where he’s been working on his solo country album.

Sources tell the New York Post, Preston, who is 10 years younger than Tyler’s daughter Liv, used to be Victoria Beckham’s assistant, but was let go — perhaps because she got too “flirty” with the designer’s soccer-stud husband, David. Preston also reportedly worked for Donald Trump’s ex Marla Maples and singer Christina Aguilera.

Tyler and Preston were looking close as far back as 2014 when they were spotted on a motorcycle ride in Hawaii, and that things are going well despite the nearly 40-year age gap.

An insider close to the “Crazy” singer says despite their love affair, they still maintain a professional relationship. “I never see them holding hands or anything of that nature when I’m around them,” says the source. “She’s always with him and always making sure his car is ready. They’re never affectionate. I was at an event with them and she was so on it.”

The insider continues, “People are always wondering [about them] and now it’s kind of finally out in the open. I think at some point, because she is always with him and does live with him, it’s like, ‘OK, it’s more than just a personal assistant.’ They’re out together all of the time. She doesn’t leave his side.”

In 2011, Tyler was engaged to another youngster, then-38-year-old Erin Brady, but they called things off in 2013. Later that year, the former “American Idol” judge was reportedly spotted making out with then-22-year-old “Hunger Games” actress Leven Rambin.

Tyler will celebrate his 68th birthday on March 26.
