Whitney Houston busted a strap on her glamorous silver sequin gown as she performed her new comeback single, "Million Dollar Bill," on last night's episode of the British singing competition "X Factor," as the video above reveals.

Houston, we have a problem!

As "X Factor" judges Simon Cowell, Cheryl Cole, and Dannii Minogue looked on, Houston sang her heart out on stage -- so much so that, at about two minutes and 17 seconds in, the strap running along the back of her dress snapped like a bungee cord.

Though the diva can be seen examining the strap at about the 2:30 mark, she didn't let the wardrobe malfunction slow down her arm-waving dance moves. And when the performance ended, the unflustered star even quipped to host Dermot O'Leary, "I sang myself out of my clothes."

We'd give Houston a high-five for being so down to earth about the incident, but then again, this is the woman who let TV cameras film then-hubby Bobby Brown help her with some, ahem, bathroom issues a few years back (and that's all we're going to say about that).

So, um, yeah, "letting it all hang out" is apparently nothing new with this gal.

But hey, at least she didn't pull a Janet!
