Perhaps the reality star's seemingly sour mood has to do with the fact that her ex Cody Simpson was spotted cuddling up to actress Victoria Justice as they were seen together at the DoSomething.org Spring Dinner in the same city. Gigi looked great despite her frown in a mostly white ensemble including lacy long-sleeve top tucked into matching ripped skinny jeans. She completed the look with a pair of olive green Adidas sneakers and accessorised with a pair of large designer shades and a black leather clutch. The daughter of Yolanda Foster had her blonde locks up in a high ponytail as she sported neutral-coloured make-up topped off with a swipe of shiny lip.
