Gastineau continues to successfully pursue modelling, which includes occasional magazine layouts. She has appeared on the cover of "Social Life" magazine, and appearances in magazines such as "L.A. Confidential" and "Life and Style". In 2008 at Fashion Week in NYC, she walked the runway for designer Tamara Pogosian, and was featured in a campaign for Ferrari California in Beverly Hills. She made small appearance in the movie Bruno where she was duped by the Sacha Cohen character into believing she was on a TV show when in fact, she was the victim of Cohen's role play.
