Susan Sarandon — Sex Symbol’s Boob Job At 70

Susan Sarandon had her luscious boobs boosted at age 70 and is now on the prowl for a toyboy lover, sources say.

“She’s used her great looks to land men in the past — why should she stop now just because she’s 70?” a source says. “She obviously loves younger men — and knows how to get them!”

The busty "Thelma and Louise" stunner showed off her chesttacular new look last month at the Cannes Film Festival — and an expert tells The National ENQUIRER the former 34D bombshell appears to have traded up to a double-D cup! Top cosmetic surgeon Dr. Anthony Youn says the 5-foot-7 brunette “appears to have had breast enhancement” surgery “with implants.”

While getting new boobs “is not common” for a woman her age, “it is not unheard of,” says the doc, who has not treated the star. “I have performed breast augmentations on women her age in the past, sometimes combined with a breast lift.”

Sources say Susan, who played naïve Janet in the 1975 cult classic "The Rocky Horror Picture Show," is putting her best bosom forward to lure a new young lover into her sexy net. She’s had a string of boytoys since divorcing her only hubby, actor Chris Sarandon, after 12 years of marriage in 1979. The beauty famously hooked up with her "Bull Durham" co-star Tim Robbins, who is 12 years younger, from 1987 to 2009. They had sons Jack, 28, and Miles, 25.

He was heartbroken when Susan dumped him for ping-pong entrepreneur Jonathan Bricklin, 40, who is a whopping 30 years younger than the red-hot mama. Ironically, Jonathan ditched Susan for a younger gal — Pablo Picasso’s 66-year-old granddaughter Marina! While the actress admitted to a previous boob enlargement, her fans don’t mind. A fan posting on the internet says: “Susan Sarandon may be 70 but her boobs don’t look a day over 30!”
