Pregnancy won't be written into 'Grey's Anatomy'

LOS ANGELES -- Chyler Leigh, who plays Meredith Gray's little sister Lexie on the ABC drama "Grey's Anatomy" is expecting her third child according to People magazine.

The 26-year-old actress and her 30-year-old musican/actor husband, Nathan West, already have two children: Noah, 5, and Taelyn, 2.

According to her representative, Leigh's real-life pregnancy will not be written into her "Grey's" storyline. Last we saw Lexie, she was getting over being rejected by George by seducing the plastic surgeon best known as McSteamy (Eric Dane).
