ET's Katie Krause sat down with Balti in our Burbank, California, studio for a Facebook Live interview on Friday, where she opened up about what it's really like posing for the magazine.
"[We wake up at] like 4 [a.m.] because you have the catch the light," the model explained. "The light in the morning is very good, so you have to be prepared, all hair and makeup done, and then you just put on bathing suits and go around and take pictures."
Balti's photo shoot may have started early, but it didn't last long. The Italian stunner -- and mother of two -- says it only took one day to get the right shot.
"I feel like the less clothes you have on, the less time it takes, because you don't really need to make an outfit look good," she joked. "The night before, we have a fitting and it took like, half an hour and they were just throwing bathing suits after bathing suits on me."
"I kept them all!" she added.
And though it didn't take long for Balti to work through the poses, the one they chose for the magazine wasn't actually that comfortable.
