Hannah Davis, DirecTV Genie and Sports Illustrated swimsuit model, is gearing up for the magazine's annual swimsuit edition. The 22-year-old was in Las Vegas with fellow rookie models Kate Bock, Emily DiDonato and others at the Caesars Palace Hotel and Casino in Las Vegas where model Chrissy Tiegen and SI.com managing editor Matt Bean hosted a live show on the Travel Channel in anticipation of the magazine's release.

Davis, who was born on St. Thomas of the U.S. Virgin Islands, is rumored to be dating New York Yankee SS Derek Jeter. The couple were seen recently sharing an intimate meal together at the Spotted Pig in New York City's West Village and have also been seen clubbing in the city together over the summer and at Gramercy Park Hotel in Decemeber, according to the New York Post.

The bright eyed newcomer is slated as one of the leading ladies for the magazine's swimsuit "rookie of the year" award, which includes past winners Nina Agdal and Kate Upton, who is covering this year's issue for the second consecutive year. Davis was actually rumored to be a legitimate possibility for the magazine's cover this year despite her rookie rank, as sources at the New York Post said that Davis made a "rare, huge first impression" on the Sports Illustrated staff and was a "frontrunnner."

However, the decision was made to go with the seasoned and extremely popular Upton, who is making her third appearance in the magazine overall. Upton will actually become one of the only SI models to cover back-to-back issues, joining the elite company of Christie Brinkley and Paulina Porizkova. 

Hannah and nine other SI models recently appeared on David Letterman's Late Night show where they delivered his 'Top 10' list, which has become an annual tradition on the program.
