The real winner of American Idol is always Ryan Seacrest. The 31-year-old host of the show – who also is the managing editor and anchor for E! News, deejays LA’s KIIS-FM morning drive-time show, and fills in for Larry King on King’s CNN talk show – has just bought Kevin Costner’s Hollywood Hills house for $11.5 million. Snatched it right out from under Gwen Stefani. It’s a shame Seacrest isn’t in a hurry to find the right lady and get married (shame on Teri Hatcher for giving us false hope), because the 10,000-square-foot Spanish hacienda sounds like a great place to raise a family, with its five bedrooms, staff quarters, billiards and media rooms, tennis court, gym, pool, and spa on one big kiss-my-grassy acre.
