Actress Tiffani Thiessen (formerly known as Tiffani Amber Thiessen) poses for a photo prior to the Las Vegas Grand Prix Charity Gala. This must have been just before she was covered in soot from the exhaust fumes of the Grand Prix itself. The photo was taken at the Bellagio Hotel and Casin in Las Vegas, Nevada on April 5, 2007. Tiffani-Amber Thiessen was born in 1974, so she turned 33 the year this photo was taken. Thiessen was best known for her roles on the TV shows Saved by the Bell (1989–1993) and the first four seasons of Beverly Hills, 90210 (1994–98).
