Ben Affleck’s naughty nanny showed why Jennifer Garner had much to worry about, as the 28-year-old stunner soaked up rays poolside in Beverly Hills.

The slender Christine Ouzounian frolicked in a barely-there black bikini at the Hotel Bel-Air — where Ben allegedly footed the bill — in images released by In Touch magazine Wednesday.

Affleck and Garner announced their breakup on June 30 amid allegations of his affair with the nanny.The ritzy hotel features room rates as high as $1,500 a night and includes a spa, steam room, private patio and waterfall.

The poolside images were taken earlier this week. Ouzounian was most recently seen Tuesday at the hotel.

Although the nanny was fired, Affleck, 42, has been paying for all of her recent pampering, reports said.

“Ben has given her enough money to cover all her bills and expenses, plus spending money, for at least the next three months,” a friend told In Touch.
