Gigi Hadid: Dreams Do Come True ... In My Undies

Gigi Hadid is living her dream in nothing more than a pair of panties and a bra ... and the whole world gets to watch.

Castings for the "Victoria’s Secret Fashion Show" recently happened and -- no surprise -- Gigi made the cut ... something she says she's dreamed of since she was a little girl.

It's her dream and every man's on November 9th and 10th.
