LENNY KRAVITZ is refusing to confirm or deny he's the man who was secretly engaged to NICOLE KIDMAN between her marriages to TOM CRUISE and KEITH URBAN. Nicole recently stunned fans when she revealed she had briefly accepted a marriage proposal before she wed Urban last year in Vanity Fair magazine.
But Kravitz insists the identity of the mystery fiance will remain a secret, as far as he's concerned. He says, "I keep that to myself. I feel like that is private and it's between the two of us, so I just leave it there."
