Father-to-be Simon Cowell is preparing to bid farewell to his bachelor pad in Beverly Hills, California after placing the mansion up for sale. The music and reality TV mogul has slapped a $20 million (£13.3 million) price tag on the four-bedroom property, which boasts a pool and sweeping views of the city and Pacific Ocean. A source tells the New York Post's gossip column Page Six, "It's a party pad, the ultimate bachelor pad. But Simon never moved in, and his life is about to change dramatically, so now he is looking for something different... (He's) searching for a new, more family-friendly mansion to bring up his son." Cowell's girlfriend, Lauren Silverman, is due to give birth to a boy early next year (14).
