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.

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