LOS ANGELES (Reuters) - Actress Katherine Heigl, an Emmy-winning star of medical drama "Grey's Anatomy," married her musician boyfriend in Utah on Sunday, US Weekly magazine reported on its Web site.

Heigl, 29, and Josh Kelley, 27, tied the knot under a marquee at a resort in Park City, Utah. Among the guests at the black-tie ceremony were Heigl's co-stars Sandra Oh, Kate Walsh and T.R. Knight, the magazine said.

Heigl won an Emmy in September for her role as an adulterous medic in the ABC network's "Grey's Anatomy," which follows the lives and loves of physicians at a Seattle hospital. She met Kelley in 2005, when she was cast in a music video, and they were engaged the following year after Heigl forced the issue.

Kelley, a critically acclaimed singer-songwriter, is due to release a new album in February.
