Livin' on the edge! Charli XCX left very little to the imagination when she hit the Brit Awards red carpet in London on Wednesday, Feb. 25. Strutting her stuff in a backless mesh gown, the "Boom Clap" singer flashed some extreme side boob — so extreme, in fact, that even she was worried about a wardrobe malfunction.

The dress, which featured all-over floral embroidery and a precariously loose web of knotted strings in the back, put the 22-year-old star within millimeters of a nip slip, a fact she seemed all too aware of.

"I've been worried about my sideboob, so I'm kinda thinking about that," she admitted to the Daily Mail outside the O2 Arena. "No one's been yelling 'Nipple!' so I think I'm okay so far."

Asked whether she thought people would actually tell her if she started showing a little too much, she quipped, "I f–king hope so. My manager's behind me, so I hope he would." 

Thank You!

She agreed, though, that she had to be careful regardless. "No finger guns," she joked.

The "Fancy" collaborator kept the rest of her look relatively simple, opting for sultry red lips, matching nails, and a loose low ponytail.
