There were rampant rumors last year that ex-boyfriend Alex Rodriguez wanted Cameron Diaz to get breast implants, and now that she's a single girl again, it seems she's taken the plunge on her own terms!

When Cameron, 39, hit the beach in Hawaii earlier this month, it wasn't a new man on her arm that caught everyone's eye but her suddenly voluptuous figure, and RadarOnline.com has photos of her bustier look.

The Charlie's Angels star, who is famous for being firmly flat chested, was suddenly overflowing from her bikini as she basked in the sun and sauntered along the Pacific.

A transgender woman who injected a bizarre cocktail of cement, flat-tire sealant and mineral oil into women to boost their buttocks could have killed her victims, RadarOnline.com has exclusively learned from a doctor who regularly performs real butt implants surgery.

"I’ve never heard of anyone using something like this, but I guess you can go to any hardware store and inject something into someone," Long Beach, California-based Dr. Marcel Daniels told RadarOnline.com. "It's a horrible idea."

As RadarOnline.com previously reported, born a man but living as a woman, 30-year-old Oneal Ron Morris posed as a doctor and charged an unidentified woman $700 for the series of butt-enhancing injections in May 2010.
