Whoa! Christina Aguilera wore a gold gown with a plunging neckline on last night's (May 7) penultimate episode of Season 2 of 'The Voice,' and she stole the show from her teammate! The dress wasn't a wardrobe malfunction waiting to happen; it was a wardrobe malfunction. Xtina went braless -- always a dangerous and risky move -- and her girls were in full view... Like popping out!

When the diva sang 'The Prayer' with Chris Mann, the last "mann" standing on her team, she looked lovely, but we were stuck by the fact that the dress was so ill-fitting. The back straps looked a bit too tight and appeared to be digging into her flesh. But the front? Oh, now that was a whole other story, as the flesh of Xtina's lovely lady lumps was in full view.

It wasn't quite a nip slip but it was darn close, as Lite 98.7 originally points out. While most of America was focused on how beautifully she and Mann sang together, up close, photographic evidence demonstrates how visible her boobs were. If she was trying to snag the spotlight from Mann, something she has been doing a bit with her team members this season, that was the way to do it.

Aguilera is a daring, curvy girl who loves to show off her ample assets, so something tells us she isn't too stressed out about displaying sooooo much cleavage or about the backlash that'll likely result from her showing off the twins.

PopCrush is issuing a memo to starlets performing in tight, dangerously low-cut gowns on live TV or at awards shows: Double stick tape. It's your best friend in these situations. It'll minimize the chance, not to mention concern, that your girls will flop around and make an unwanted cameo, if you pick up what we're putting down. Use a little and that way, you can focus on looking and sounding beautiful without the threat of a nip sloop or booby flash.
