American supermodel Kate Upton, 26, who is expecting her first child with baseball star Justin Verlander, 35, is reportedly finding it difficult to deal with her changing body during pregnancy. "Kate has massive b**bs and they're only getting bigger. They're starting to weigh her down already. She's worried about how enormous they're going to get as her due date approaches," a source told US entertainment website RadarOnline.com. And since Upton is not sure how readymade clothes and lingerie would look on her, she is currently opting for only tailor-made stuff.
