Sports Illustrated model Kate Upton appeared to be rounder in shape when she was spotted at boyfriend Justin Verlander's baseball game Monday.

Upton was cheering on Verlander during the Detroit Tigers and New York Yankees game when he tossed her a ball as she sat behind the dugout. A video of that moment was captured and made the rounds on the internet, which fueled rumors that the model could be pregnant due to her fuller figure.

More speculation arose when she was spotted shopping with her friend Lily Aldridge in New York City on Aug. 3 wearing a loose fitting floral dress, a departure from her usual form-fitting outfits. The Hollywood Gossip also claims that Upton made a toast with water instead of champagne during a dinner date with Verlander.

Moreover, Hollywood Life is reporting that although Upton looks flawless on the September 2014 cover of Elle magazine, the model's wardrobe appears to be a little less revealing than usual.

For the cover shot, Upton is sitting down and wearing a black one-piece underneath an oversized jacket. Another photo shows the model wearing a multi-layered dress with a vivid design that completely hides her figure.

The website is also reporting that the behind-the-scenes video from Upton's cover shoot shows her walking around while trying on different coats, and apparently her midsection was covered at all times.

Upton has been both praised and criticized for being more full-figured than the average model. She has admitted in previous interviews that she's had to endure body related issues and is often ridiculed for gaining weight. Though she may still have some insecurity about her shape, she told OK! magazine recently that she has learned to take it all in stride and feel good about herself.

"I still have body insecurities all the time. But when I'm feeling insecure, I still live and go out and have fun," said Upton.
