Will Casey choose the nerdy but sweet Mona? Or perhaps the preppy Stella, or the fit and focused Clarice? Will she be tempted by the artsy and edgy Vette or the mischievous but lovable Harper? Or will the stylish Bethany win her heart? Or will tree-hugging Leyla catch her eye? WHY NOT THEM ALL?!?! All seven can get Casey pregnant. Each girl's last name is in all caps to make it easier for Kelsey to identify the potential moms in the wild. #kelsey100babychallenge
