Lenny Kravitz! heatworld is wondering just how Nicole Kidman managed to pull this one off under the constant gaze of the world’s press – we knew they'd dated, but had NO idea there was a secret engagement. See, yet another example that you can lead your life out of the spotlight if you really want to – take note Jude, Gwyneth et al. Normally reserved Nicole dropped a couple of bombshells in her latest Vanity Fair interview – the first being that she and Tom Cruise sadly lost a baby early in their marriage. But she also revealed she was engaged to a mystery man sometime after she and Tom split and before she married Keith Urban – and that mystery man was Lenny Kravitz. “They were even house-hunting for a while!” a source revealed. Lenny's rep said, "I cannot confirm or deny it" and Nicole's simply said, "I don't know." They ALWAYS completely deny everything, so for them NOT to deny it is as good as admitting it!
