The actress and her husband, Dean McDermott, purchased this home in February 2008 via a Trust for $2.275M. She is known for being Aaron Spelling's daughter and for her role as Donna Martin in the 1990's teen soap opera "Beverly Hills, 90210".
Here's a great listing site with photos (pre-renovations). Clearly on the show, a different home is shown from the exterior front... probably to try to throw off paparazzi. http://www.1955thayer.com/
