Katherine Heigl, who plays Izzie on Grey's Anatomy, is off the market. According to People magazine, she and musician Josh Kelley are engaged. The couple started dating last year after Heigl appeared in one of Kelley's music videos. Kelley says, after the shoot, he insisted she come out for drinks and they've been hanging out ever since.

In case you're wondering who Josh Kelley is, he has recorded two albums and sounds sort-of like a cross between John Mayer and Teddy Geiger and you can hear him on his website. Kelley has a third album coming out on July 24th and on it is a song for Heigl, called 'Katie's Song'.
