After the blonde beauty attended the Hollywood premiere [see below] of her new film Paradise, she hung out at the after party with friends — and Ari showed up to support the starlet.
"She socialized with director Diablo Cody for a bit, then moved outside to sit on a couch on the patio with her pals," an eyewitness at No Vacancy tells Life & Style. "She was looking at her phone and started putting on lip gloss and primping. Shortly after, Ari arrived!"

And the pair were ecstatic to see each other. The 25-year-old's group even left to give them space!
"They sat close together on the sofa and talked for about 45 minutes straight. They were both very engaged in the conversation," says the onlooker. "He would lean in and whisper in her ear from time to time. It was definitely playful and flirty!"
Around 10:30 p.m., Julianne and Ari made their way inside to chat up Diablo. They then sat at the bar.
"She perched herself up on a stool and continued to talk to Ari," the eyewitness tells Life & Style. "The party was dwindling down at this time, but they didn't seem to mind and carried on talking. They definitely have chemistry!"
The actress was first spotted hanging out with Ari in mid-July — four months after she and Ryan Seacrest called it quits after nearly three years of dating.

As Life & Style reported, a source close to Ari tells the mag that the filmmaker may not be the ideal guy for the Safe Haven star.
"[Ari] is a ladies' man," the insider recently told Life & Style. "He dates and goes out with so many women, he's such a player."
Here's hoping he's changed his ways for Julianne!
