Biel was meeting up with hubby Justin Timberlake at the Dream Downtown hotel in NYC after the MTV VMAs on Sunday, when the supposed wardrobe malfunction occurred.
Showing off her hot curves, Biel donned a sheer, see-through Dolce & Gabbana dress, with just a little bit of lining to keep it legal.
As the 31-year-old star whisked past the photographers outside the hotel, they snapped a pic that appears to show a bit of panty.

Funny enough, Justin's ex Britney Spears wore a similar Dolce & Gabbana dress to the VMAs in 2001!
