The "Desperate Housewives" actress told The Associated Press that her repeat selection for the No. 1 spot was a shock.
"I was actually really shocked last year when I made the list," said the 31-year-old Longoria, who ranked No. 91 on the 2004 roster.
"So 91 to No. 1 was a big jump, and then to get it a second time in a row -- I just couldn't believe it," she said Friday. "I was like, `Surely there are more beautiful women in the world.' I can name 10."
Maxim said it is the first time the magazine has bestowed the No. 1 honor back-to-back. Editors made the selections for the issue, which will be on newsstands Thursday.
The magazine said all of the women on the list have several things in common, including "a tremendous amount of buzz surrounding them, undeniable beauty and a promise of greater things to come."
Jessica Alba is No. 2, followed by Lindsay Lohan, Angelina Jolie, Stacy Keibler ("Dancing With the Stars"), Scarlett Johansson, Cameron Diaz, Kate Bosworth, Keira Knightley and singer-actress Christina Milian.
The list also includes "Desperate Housewives" stars Nicollette Sheridan (No. 48) and Teri Hatcher (No. 73).
"I would have voted all of our `Housewives' on the list," Longoria told the AP in a phone interview.
"The Maxim Hot 100 continues to get hotter, and it is all because of girls like Eva Longoria, who always looks sensational and continues to reach new heights in her career," Editor in Chief Ed Needham said in a statement Monday.
What does boyfriend/San Antonio Spurs star Tony Parker make of all this?
"Oh, he's very proud," Longoria told the AP. "He thinks he's with a beautiful girl every day, so for him, it's, you know, someone else solidifying what he already thinks."
