Mumbai: If you thought Saif Ali Khan had crossed enough bridges to last him a lifetime, here’s more on the guy. On Wednesday he walks the ramp for the first time for Provogue.“Yes, it’s my first walk on the ramp. It’s actually for the brand that I endorse,” Saif said. “They’ve asked me to walk the ramp. I’m supposed to be the closing act for their fashion show and I’m nervous as hell.”
