Now that husband Aaron’s dead and the two kids have their own places, Candy Spelling must find the 123-room Holmby Hills mansion rather empty. Even though the widow Spelling will miss the Manor’s two rooms relegated solely for gift-wrapping, she’s putting the whole 56,500 square feet of white-elephant real estate up for sale. The house, which cost $47 million to build in 1991, will probably be listed for $150 million with the Westside Estate Agency and she’ll most likely be sniffing around for smaller, more modest digs. If Manhattan smells good to her, we suggest she look no further than the 16 rooms on the top three floors of the Pierre Hotel (top right) at Fifth Avenue and 60th Street. Reasonable at $70 million.
