EXCLUSIVE: Ben Affleck's Former Nanny Shows Off a Brand New Lexus

This nanny isn't hiding her lavish lifestyle!

Christine Ouzounian no longer has a job as Ben Affleck and Jennifer Garner’s nanny, but she doesn’t seem short on cash. 

ET has obtained this Instagram from the 28-year-old’s account – she captioned a photo of herself with what appears to be a Lexus IS convertible, a car that starts at about $43,000. “Keep Calm and meet my new drop top Lexi,” Ouzounian wrote, accompanied by a smiley face emoji.

She posted it all to Instagram on Monday. Over the weekend, the ex-nanny also posted a paparazzi photo of herself, quoting an Alicia Keys’ song in the caption, “She’s just a girl and she’s on fire.” That marked her return to social media – she had stayed quiet since the scandal about her and Affleck broke weeks ago.

ET can also confirm Ouzounian is still staying at the pricey Hotel Bel-Air, where rooms run about $1,000 or more a night. She’s entertained a close pal at the swanky spot, dined at Wolfgang Puck’s restaurant and treated herself to spa treatments, spending a reported tens of thousands in all. According to a source, Affleck has not been seen at the hotel.

Ouzounian certainly experienced a lavish lifestyle while working for A-listers Affleck and Garner. She traveled to the Bahamas with them and stayed at the exclusive Baker's Bay resort with the family, where celebs like Tom Brady and Gisele Bundchen also vacation and own property.

ET can also confirm Affleck took Ouzounian to the decadent Venetian hotel in Las Vegas for a charity poker tournament after that stay in the Bahamas. That trip raised red flags for friends of Ouzounian, who wondered why she’d be jetting off (on a private plane, of course) to Las Vegas with Ben, but not his kids.

As for Ben, he’s focusing on work and family – watch the video for info on his latest trip to Atlanta to see his estranged wife and their three children. He has denied a romance with Ouzounian.
