Ben Affleck’s Playboy model girlfriend Shauna Sexton flaunts …


She’s catapulted herself to instant stardom after being photographed with Ben Affleck right before he entered rehab a month ago.

And Shauna Sexton isn’t letting her 15 minutes get away from her.

The Playboy model, who quit her veterinary technician job after hitting the headlines, put on a busty display as she headed to the beach in Malibu on Sunday.

Shauna, 22, sported a skimpy black bikini top, making sure to leave the bodice of her on-trend romper open to reveal her cleavage.

The skimpy outfit showed off her long tanned legs as she headed to the sand carrying a towel and a paper bag of supplies.

She wore her hair tied back from her face and rocked a pair of purple tinted shades.
