"She looked like a Hollywood star even then. She wore her hair shorter, above her shoulders and styled like an old-fashioned movie star. She loved it like that," the paper quoted him, as saying.
"She was very boisterous and loud and enthusiastic about everything she did in life.
"She was the leader of the pack with her friends and she'd pursue a guy if she liked him. She was totally unabashed about shouting out, 'Oh look at that guy, he's cute!'"
Baroni, now a Los Angeles lawyer, also reveals that like her Friends character, Aniston was never without pals in her childhood.
She had friends in the choir, drama group, basketball and volleyball teams at New York's LaGuardia Arts High School.
However, while she was very willing to make friends, Aniston steered clear of relationships, and had only one serious boyfriend name Nick before she met Michael.
In fact, she once told Michael about an incident when she and Nick were kissing so enthusiastically that their braces locked together.
The teens were found by her mum Nancy, who took them to an emergency dentist who used pliers to disentangle the two. Jennifer, as Michael revealed, almost died of embarrassment.
Michael also revealed how he hooked up with Aniston at the party in New York, after he spotted her going into the kitchen to get a drink.
"I followed her in and then shut the door behind me. I grabbed her by the shoulders, spun her round and kissed her. Luckily, I didn't get slapped," he said.
When it was time to go home, Jennifer gave him her phone number in red lipstick on a scrap of paper.
"It was very sexy. She was physically mature and emotionally mature," he added.
And though the two became close over that summer, they decided to call things off before it all got too serious.
Michael says: "We were both getting a little uncomfortable with how we felt about one another. We both agreed that we were young and starting to feel serious about someone wasn't a good idea... probably."
