Young “Kick-Ass” star Aaron Johnson should be spending his free time partying at the Chateau Marmont and sucking face with the starlet du jour.
Instead, the 19-year-old Hollywood newcomer is home with his pregnant fiancée — who’s old enough to be his mother.
Johnson said he doesn’t need to sow any wild oats, because he’s found true love.
“I’ve got a wonderful woman,” Johnson said recently of gal-pal director Sam Taylor-Wood, who at 43 is more than twice his age.
“She’s lovely, and she’s a fantastic mother. ”

Taylor-Wood, who is currently seven months pregnant with Johnson’s baby, met the hunky star when he was cast as the lead in her 2009 flick “Nowhere Boy,” about John Lennon’s childhood.
From the moment they met, Taylor-Wood said, she knew it was lights, camera, love.
“We had quite a psychic link,” she told The Guardian newspaper in England. “I felt that link almost from Day One of meeting him.”
Taylor-Wood, who was married to art dealer Jay Jopling until 2008, has two daughters from that union, ages 13 and 3.
Johnson says he’s now preparing for his new role — as a dad.’
“It’s not scary,” he said. “I’m already a stepdad anyway. So the nerves have sort of gone.”
Both halves of the odd couple insist they’re well-suited for each other, even if their birth certificates say otherwise.
“It’s not unusual,” Johnson told Britain’s Sunday Independent newspaper in December, just months after they hooked up.
“I’m an old soul, and she’s a young soul.”
Taylor-Wood said her views of love and life were shaped by multiple bouts with cancer.
She courageously fought colon cancer in 1997 and then staved off breast cancer three years later.
Those life-and-death battles, the moviemaker said, have helped her tune out any snickers about hooking up with a much-younger boy toy.
“Going through all the crap I’ve been through, I don’t really listen to other people’s opinions,” Taylor-Wood said.
“[I] just follow my heart and my instincts.”
Johnson also insists he doesn’t care what people think.
“People have their judgments and opinions and it’s almost like other people live by a rulebook and I don’t,” a defiant Johnson said.
“I don’t live by rules and I do what I want to do and I’m out there and I’m an outspoken presence and I go with what I feel in my heart and in my soul and travel by that, not by what other people expect.”
The couple plans to have a private wedding ceremony and haven’t given any hints of when and where the celebration will be.
Johnson said his folks have given them their blessing.
“They are really proud and supportive,” he said.
A friend of Taylor-Wood said the moviemaker couldn’t be in better spirits.
“I’m pleased for Sam, she’s really happy and she’s changed her life so radically, it’s amazing,” said artist Tracey Emin.
“It just goes to show what a year can do to someone’s life and Sam deserves all the happiness she can get.”
