What is it about David Spade that makes him so irresistible to the opposite sex? Does he emit some sort of hypnotic musk that drives hot women crazy? Or has he mastered a seduction technique that his average-looking brethren would kill to possess? Whatever the case, the guy who has wooed everyone from Heather Locklear to Nicollette Sheridan, Julie Bowen to that Playboy model he impregnated, was spotted out this week with sublime "Top Chef" host Padma Lakshmi. The aesthetically mismatched pair was snapped exiting Los Angeles eatery Koi together on Wednesday night before driving away in the funnyman's car. So, was it a date or just a friendly meet-up? Your guess is as good as ours: Lakshmi's rep didn't respond to our request for comment on the nature of their relationship. Padma, who divorced Salman Rushdie in 2007 and has frequently been seen in the company of 70-year-old billionaire Teddy Forstmann, welcomed daughter Krishna in February (the father is believed to be businessman Adam Dell). Spade became a dad in 2008 when model Jillian Grace gave birth to his daughter after a brief romance.
