These days, the model-actress is happily coupled up with actor Tom Sturridge, the father of her baby girl Marlowe. But Sienna hasn't always been the best partner, a fact she fessed up to during an interview with Esquire U.K. in early 2014. (When asked if she'd ever done anything immoral, the actress responded, "No, no, no, I have.") Was she referring to the affair she had with "Layer Cake" co-star Daniel Craig while she was engaged to Jude Law -- or the affair she had with Balthazar Getty while he was still married? Maybe Tom Sturridge should watch his back!
