Some have waited a whole year for the release for Sports Ilustrated's most awaited issue. And the good news is, you'll not only get one hot model, this year, you'll get two.

Two of the nation's most favorite cover models, Kate Upton and Katherine Webb, will be in Sports Illustrated Swimsuit edition for this year. Two for the price of one. That's certainly enough reason for all the fanatics to be thrilled.

Although Upton will be on the cover, Webb may cause the hype since she is offering something new to the readers. For all the swimsuit photos, the Sports Illustrated website has posted several hot bikini pictures of the models for public viewing. They also posted some teaser photos on their official Twitter account.

But aside from the website photos, Sports Illustrated even brought the anticipation to a higher level with a short clip video. The behind the scenes footages showed the models in all their goddess-like figures while working on the shoot.

To continue the promotion before the magazine's official release on February 12, Kate Upton, Katherine Webb, Chrissy Teigen and Hannah Davis will be on "The Late Show With David Letterman."

Earlier today, Kate Upton tweeted a photo with the girls while they were in the dressing room, ready to be called in for the show.

What's exciting about the magazine now is the model that the website is presenting besides Kate Upton. Katherine Webb should be excited for the attention she is about to receive.

Sports Illustrated also launched a new part of their website called "Swimsuit Daily." On Monday, they featured a whole bunch of Webb goodness. Though Upton and Webb may offer different flavors to the readers, there's not a doubt that a lot of fans are anticipating the magazine's release.
