Stop whatever you’re doing! Jennifer Lopez has suffered ANOTHER nipple slip.

And she was wearing the exact same dress as her embarrassing wardrobe malfunction earlier this month.

She was singing at the O2 Arena on Monday night and accidentally gave the London crowd a flash of her left breast.

It’s nice that she was considerate enough to show us something new, after her right bosom popped out last time.

We’re starting to think the nip-slip is part of her choreographed routine. It’s a bit awkward seeing her boob again, like saying goodbye to someone and then walking the same way.

There it is! ( Image: PCN)

Who’s got the top boobs in showbiz? From Holly Willoughby to Kim Kardashian – it’s the best of the breast!

J-Lo wears the same sequin jumpsuit every night of her tour but now the fancy frock has given her style mishaps on two occasions, she might want to sack her stylist or consider using some double-sided tape.

And if you were wondering what the right boob looked like… ( Image: WENN)

We went along to J-Lo’s first ever concert in London, 3am’s Rachael has described it as “an explosion of sound and colour”.This bloke is just making sure she’s covered up. It’s a tough life. ( Image

Jenny – who is always eager to remind us she’s from the block – was performing in Bolognia, Italy on October 11 when the same thing happened.

Ever the professional, J-Lo wasn’t bothered that her nipples wanted to get a peek at the tens-of-thousands of fans and carried on her amazing performance.

She doesn’t have to feel to flustered about the whole thing. It happened to Kim Kardashian’s mum yesterday and here’s a hilarious gallery of the BEST celebrity nipple slips. Enjoy.
