We're green with envy.

Lovely singer/actress Katharine McPhee dons a fedora and green & white stripped bikini to soak in some sun in beautiful Santa Barbara, California on Tuesday, and Breaking Celebrity News has the pics.

In addition to her singing and acting career (McPhee appeared in the 2008 comedy The House Bunny and has made guest spots in various TV shows), she recently threw her support behind a program called Hunger-Free Summer Initiative For Kids, designed to help parents who rely on free or reduced-price lunches to feed their children during the school year.
