The girls head to a theme park where they must pose while riding a rollercoaster. This week's photo shoot takes the girls underwater as they are photographed by top beauty photographer Matthew Rolston, who is also this week's guest judge.

The final three models face off and go head-to-head with two major photo shoots and an extended catwalk challenge. The first shoot is shot by world famous photographer, Timothy Greenfield Sanders, and the second is done for Cosmopolitan magazine, captured by famed celebrity photographer Marc Baptiste. A final twist comes as the models are each surprised with a visit from a family member, who accompany them to a SoHo art gallery where their best shots are on exhibit. Fashion photographer and music video director Matthew Rolston joins the four judges for the final deliberation.

In the season finale, Billy, Joel and Julia do a sexy photo shoot for People magazine. Their inner beauty is tested by an interview with executive editor Jess Cagle.

The remaining models get a dose of what the modeling world is really like as an A-List photographer flies in for a final high-profile shoot. With only four models left, the competition gets fierce as they prepare for one of their final catwalks. Also available on iTunes
