This one's a tearjerker! Allie Ayers had the best reaction to being named a finalist in the #SISwimSearch open casting call, and we've got the footage to prove it.

In the cute video she posted to her YouTube page, the blonde beauty is set up by a friend to think she's modeling bikini tops, but instead she gets a phone call that will change her life forever.

On the other end of the line is none other than our editor MJ Day, telling an ecstatic Allie that she is a finalist.

Allie begins to cry and the rest is history!

The journey for Allie started in April when over 5,000 girls submitted Instagram videos to become part of SI’s first-ever open casting call and model search. In May, we cut the 5,000 submissions to 35, and invited them to our Brooklyn office. The 35 became 15, who who joined us in Miami to model SI's debut swimwear line.

The final six, including Allie, were announced Wednesday. These bombshells will officially appear in the pages of SI Swimsuit 2018 as a part of this year's Model Search class. From these six, one lucky lady will be selected as the winner of our competition and earn a place as an SI Swimsuit 2019 rookie.
