Nina Agdal, Lily Aldridge, Chrissy Teigen make cover of SI Swim Issue

The 50th anniversary of the Sports Illustrated Swimsuit Issue celebrates the the past, present and future with three models on the cover.

Sports Illustrated revealed the cover of its annual Swimsuit Issue on Thursday night. The 2014 edition of the now-iconic cover photo is a beach shot featuring a triple threat of recognizable models in Nina Agdal, Lily Aldridge and Chrissy Teigen.

Adal (far left) was named the "Rookie of the Year" in the 2012 edition of the swim issue, while Aldridge (center) broke through with Victoria Secret before making her SI debut and Teigen (far right) earned "Rookie of the Year" honors after her debut in the 2010 edition.

The issue will celebrate the past, present and future of swimsuit fashion (oh yeah, and the lovely models that have worn them) as depicted by Sports Illustrated and its photographers.
