The "Transformers" starlet reveals that she's had less sexual partners than the public might assume.

"I've only been with two men my entire life," she says in the April issue of Harper's Bazaar, according to HuffPo. "My childhood sweetheart and Brian."

"Brian" is actor Brian Austin Green, to whom she was once engaged. They've been together off and on, depending on what month it is.
