Grey's Anatomy star Ellen Pompeo displayed her own extra anatomical features while on a stroll in California, the Daily Mail reported.

The actress, 40, appears to suffer from a condition known as polydactyly, a congenital physical anomaly in humans that results in extra fingers or toes.

In pictures taken as she walked with her husband and daughter, Pompeo's brown leather flip flops showed she has an extra toe on each foot.

She gave birth to the couple's first daughter, Stella, in September last year.
