There's no contest. I (as well as you) would rather stay in Brad and Angelina's estate on Long Island instead of Jon and Kate Gosselin's old dumpy house in Pennsylvania.

Price: $12,800,000. The estate, called
Rosehearty, is 10,000 square feet, has 11 bedrooms, 7.5 bathrooms, a heated and air conditioned guest
pool house/cottage, a beach cabana on the 260-foot stretch of private beach facing the lapping shore of Oyster Bay Harbor, swimming pool, tennis court, extensive gardens and rolling lawns.
Price: $325,000.
Listed on the market for 89 days. Has 5 bedrooms and 2.5 baths.

I placed the Gosselins as C-Listers because they get way more press coverage than Kathy Griffin.
