Steven Tyler and Aimee Ann Preston were quite the stylish duo when they showed up hand in hand to Bulgari at the 24th Annual Elton John AIDS Foundation's Oscar Viewing Party.
The 67-year-old musician paired a loose-fitting black shirt with snazzy pants and, of course, was wearing lots of jewelry. Tyler's date -- his longtime assistant -- was also striking in a figure-hugging tan dress and nude pumps.
This isn't the first time Preston, who is 39 years younger than Tyler, has been photographed with the Aerosmith frontman, but it's the first time there has been any sign of PDA. Two years ago, Preston posed with Tyler and John Mayer, and has also been pictured alongside the rocker and Lady Gaga.
Despite romance rumors over the years, Tyler has never spoken on his relationship with Preston. Prior to working with Tyler, a source tells ET that Preston -- who is from Denver, Colorado -- also worked with Donald Trump's ex-wife, Marla Maples, Christina Aguilera and the Beckham family.
The former American Idol judge wasn't the only celebrity who had a new girl on his arm on Oscars Sunday, Feb. 28. Henry Cavill, 32, and his 19-year-old girlfriend, Tara King, made their red carpet debut at the Vanity Fair event.
"People say age is just a number. It's actually a real and true sign of someone's maturity," the Batman v. Superman star told ELLE of their 13-year age difference. "But in this case, she's fantastic."
