U.K. TV star Michelle Keegan has been named the hottest woman in the world by British magazine Zoo.

A virtual unknown in the United States, Keegan, 25, plays Tina McIntyre in the popular soap opera "Coronation Street." She is also famous for having once been engaged to The Wanted singer Max George.

The actress made headlines overseas earlier this month after a photo of naked breasts appeared on her Instagram page. The image was quickly deleted.

Keegan denied the photo was a selfie and posted on Twitter: "Twitters going crazy! … Sorry to disappoint guys, but they’re not mine! Hahahahahaha!!!!! #Brilliant x"

There are several familiar faces on Zoo's Hot 101 list. Sports Illustrated swimsuit model Kate Upton came in second place, while  Mila Kunis (#6), Rihanna (#7), and Jennifer Lawrence (#10) made the top 10.

Thousands of Zoo readers participated in the poll. British glamour girls Leah Francis, Alice Goodwin, Jess Kingham and Melissa Debling round out the rest of the top ten.
