Jessica Alba and George Clooney have been named the "most desired" single celebrities.
The Hollywood stars topped a poll by internet dating website Yahoo! Personals asking members which celebrity they would most like to romance.
Susan Mernit, the Yahoo! dating expert, said: "It is obvious both George Clooney and Jessica Alba are top of people's lists when it comes to 'sexiest celebrity'.
"In addition to people finding them physically appealing, it doesn't hurt that they have both maintained a clean reputation while living in front of
the cameras. That combination is most likely why our survey's respondents find them so desirable."
Clooney fought off stiff competition from Sahara actor Matthew McConaughey and hip-hop star Kanye West to be crowned Most Desired male.
Alba took the title of Most Desired female ahead of former Friends star Jennifer Aniston.
Hairspray actress Queen Latifah and Irresistible singer Jessica Simpson also featured in the top five.
It is not the first time Clooney and Alba have prevailed in such polls. Last month, Clooney was named the Most Eligible Bachelor in Los Angeles by Forbes.com, and was voted the Sexiest Man Alive by People magazine for the second time last year.
Earlier this year, Alba was hailed as the Sexiest Woman in the World by FHM magazine.
