ET was with Sports Illustrated's first-time swimsuit models after they got to see their sexy photo spreads for the very first time.

Ashley Graham, who is a size 14-16, shed tears when she got the announcement that she would be featured in the Sports Illustrated Swimsuit Issue as an official model -- the second official "plus-size" swimsuit model in the history of the magazine.

"This is huge. This is phenomenal!" the 28-year-old model told ET. "This has broken down a huge barrier."

Models Barbara Palvin, 22, and Bo Krsmanovic, 23, were equally as thrilled with how their photos turned out.

"It's really good!" Bo gushed, while looking over her picture for the first time.
