Kate Upton sparks pregnancy rumors during outing with Lily Aldridge

NEW YORK, Aug. 4 (UPI) -- Kate Upton sent the rumor mill for a spin after stepping out in New York City on Thursday sporting a loose fitting dress.

The 22-year-old Sports Illustrated cover girl was shopping with fellow model Lily Aldrige when pictures of her in a baggy orange dress prompted several media sites to speculate she's pregnant with boyfriend Justin Verlander's child.

The model complemented her controversial dress with beige sandals, a white crossbody bag and dark shades. Aldrige, on the other hand, wore tight shorts, a crop top and converse for the outing.

Rumors triggered by Upton's curvy frame come days after the model confessed she used to "beg" for the body she has in an excerpt from the September issue of Elle U.K.
