Former THE Brady Bunch star Christopher Knight threatened to leave his model wife ADRIANNE CURRY when she posed for sexy lesbian photos - as a birthday gift. The incident, which was caught on camera for upcoming reality show My Fair Brady... Maybe Baby, left the upset actor suggesting the couple separate. The girl-on-girl photos, which Curry has since repeated with a pal for Playboy magazine, were supposed to end a feud over baby plans - but they started a new one. In the tense episode, which will air in January (08), Knight says of the photo gift, "It is the physicalisation of my worst fears. It creeps me out. I want a separation."
