Happy birthday to you, Hannah Davis

Our 2015 SI Swimsuit cover model turns 25 today and we invite you to join us in sending over love and birthday wishes on her big day. Starting the celebrations early, Hannah joined our team in Las Vegas over the weekend to host a SI Draft Day Viewing Party and join the ladies of SI Swimsuit at the Foxtail Pool Club for the Official SI Fight Weekend Party

Jet setting off to Empire City next, Hannah appeared at the Yonkers-based casino to greet fans, host an exclusive Kentucky Derby viewing party, and even judge a Derby hat contest! If we do say so ourselves, Hannah was hands down the winner as she rocked a vibrant straw hat paired with a luxe jumpsuit for the event.

As if all that weren't enough, Hannah managed to squeeze in fittings for her and beau Derek Jeter just in time for the duo to make their red-carpet debut as a couple at the highly anticipated Met Gala. The birthday girl stunned in a classic red gown with sexy cutouts and a gorgeous thigh-high slit.

While we're sure the infamously humble Hannah will opt for a comfortable and cozy night in, we couldn't help but shower her with a little (read: a lot) of attention for always being such a shining star in the SI Swimsuit family! Happy birthday, Hannah—we love you!
