Las Vegas was a little extra hot last night (February 13) as the ladies of the Sports Illustrated Swimsuit Issue showed up for the On Location event.

Chrissy Teigen, Anne V, Jessica Gomes, and Katherine Webb all got plenty of attention as they arrived on the red carpet outside the Marquee Nightclub at The Cosmopolitan of Las Vegas.

And of course, cover model (for the second year in a row) Kate Upton stole the show in her halter-style striped purple dress as she worked her magic for the shutterbugs.

Earlier this week, Kate told the “Today” show that she had a rough time getting the money shot while working in Antarctica, and afterwards it only got worse.

"It was freezing ... I'm from Florida, so it wasn't great for me. Obviously, the pictures now ... it's incredible. I can't believe we were all able to accomplish that."

"When I came back I was losing hearing and eyesight because my body was shutting down it was working so hard to keep me warm,” added Upton.
