Jennifer Aniston reportedly flirted with actor at a recent Christmas bash.
"Jen and Adrien were flirting with each other outrageously -- you could totally tell that they're an item," a source told The National Enquirer.
"At one point, Adrien was leading Jen away in hand. She was rubbing her hands down his back and gazing into his eyes like she was totally smitten.
"Jen is definitely very taken by Adrien, who has been a close acquaintance of hers for a long time.
"He's a charming, intelligent guy who has no pretensions about him whatsoever, so Jen always feels at ease in his company.
"And besides the fact he isn't insecure about her success, she loves the dangerous, edgy side to him. He exudes this rugged sex appeal that Jen gravitates towards. But she needs to be careful."
