Tricia Helfer, Jenna Jameson, Katharine McPhee, Others are Sexy

This just in: Tricia Helfer is sexy.

Fans of Battlestar Gallactica - and hot women in general - are shocked by that, we know.

But it's now official: the actress has been listed at #63 on FHM magazine's ranking of the 100 Sexiest Women in the World.

Who joined this blonde goddess?

Model Marisa Miller was considered the tenth hottest babe. Here are a few more from the poll:

88. Rachel Bilson. She's moved beyond Summer Roberts and The OC by now. And while she may be in the arms of Hayden Christensen, she's also in the hearts of men everywhere.

65. Megan Fox. Will star in this summer's blockbuster, Transformers. May also star in the fantasy of many men after this quote: "I have the libido of a 15-year-old boy. My sex drive is so high. I'd rather have sex all the time than leave the house."

37. Jenna Jameson. Yes, a porn star can still be sexy.

Even when the mystery of Jenna Jameson nude is pretty much gone at this point. Helping this hottie's cause? She has been rumored to have had a sexual tryst with Jenny McCarthy.

21. Christina Aguilera. Remember when there was a debate between her and Britney Spears?

Seriously, we weren't sure who was sexier a couple years ago. Now, though? Let's just say we're very jealous that Jordan Bratman gets to see Christina Aguilera nude every Sunday.

2. Katharine McPhee. With apologies to Haley Scarnato and Antonella Barba, this is the true American Idol beauty.

While Taylor Hicks may have somehow beat her out as last year's champion, few top Katharine McPhee in the looks department.

1. Jessica Alba. We agree. Damn that Cash Warren.
