Now that the America's Next Top Model field is narrowed to the final four runway wannabes, the girls are starting to miss home more than ever.

Traveling in Sydney for a series of photo shoots, Model's Natasha, the sharp-tongued Russian beauty, expresses her love for her (rent-a) hubby, Stuart, over the phone while the other girls listen in.

As our UsTV sneak preview clip shows, the other girls are none too happy with Miss Natasha's Public Display of Affection, which was one or two breathy "I Love You's" away from phone sex. Leave it to level-headed Renee to set the record straight, though. "She's psychopathic," she reasons with the camera. "She's weird." Thanks for clearing that up, Renee!

Will tensions continue to mount in the Sydney house? Which girls will make the coveted top three? Turn on UsTV right now for a sneak peek and catch the full episode tonight on the CW at 8 p.m.
