Kate Upton and her boyfriend Detroit Tigers pitcher Justin Verlander took the Ice Bucket Challenge together but it is Kate's outfit that's getting all the attention. Pregnancy rumors are swirling around the couple after the swimsuit model opted for two oversized t-shirts rather than a fitted tank or a bikini for the Challenge. Upton's appearance on Live with Kelly and Michael also contributed to the rumors. And lately the model's Instagram has featured more loose cut clothing over the last two months.
