Thank God for underwear.

She's never been shy about showing off her curvy figure, but Mariah Carey is really stepping things up a notch! During a performance in Sydney, the newly single songstress strutted her stuff across the stage in a completely see-through gown that left little to the imagination.

Well hello there, Mariah's undies. Fancy seeing you here!

We're not exactly sure what's going on here. This may be a cry for attention or just her way of showing ex-husband, Nick Cannon what he's missing, but for some reason Mariah is totally cool with rocking this sparkly number that completely shows off her goods. (Have you not learned ANYTHING, Mimi?!)

The singer's rep confirmed her break-up with Cannon in August claiming, "Mariah is focusing on her children and her upcoming tour."

The tour runs until the end of 2014 and her final performance will be in NYC.
