Alessandra Ambrosio Wardrobe Malfunction, Underwear Flash PHOTOS: 'TMNT' 2 VS Angel Dress Fail

Alessandra Ambrosio might have had a major wardrobe malfunction at the recent InStyle Awards. Before appearing in TMNT 2, aka Teenage Mutant Ninja Turtles: Half Shell, the Victoria's Secret model teases a bit of her underwear, or lack thereof, in a sizzling set of photos.

As we mentioned before, the brunette bombshell will not be portraying a fictional character from the popular comics. The Victoria's Secret model will be starring in the highly anticipated sequel as herself. Lucky cameraman Vernon Fenwick (Will Arnett) ends up having a steamy date with the supermodel after the events of the blockbuster hit, Teenage Mutant Ninja Turtles.

According to Daily Mail Online, the gorgeous 34-year-old flaunted her sexy figure wearing a slinky white dress. The outfit had diamond shaped cut-outs down on each side. The risqué cut-outs revealed that she wasn't wearing any underwear to the event. You can definitely tell something is amiss when the model shows off her bare bottom.

The fishtail gown lead all the way to the floor. The steamy ensemble teased the brunette beauty's plunging neckline, highlighting Alessandra's cleavage. The straps were encrusted with beads and sequins.
