Rita Ora flashes boob at Lovebox festival - The Sun

The saucy incident occurred when the R.I.P. singer was performing at London's Lovebox music festival yesterday.

Her lacy white top was unable to hold in her curves as she leapt around on stage, accidentally revealing a nipple to the audience.

But she didn't let a little nudity stop her set, sorting her top out and carrying on with the rest of the gig.

And it didn't ruin her enjoyment of the concert, as she later tweeted: "LOVEBOX THANK YOU FOR TODAY. YOU WERE AMAZING."

The 21-year-old's outfit was racy even before her wardrobe malfunction, with a pair of see-through trousers showing her underwear.

And it's not the first time she has suffered a fashion disaster, as she went without a bra on a trip to Cannes Film Festival last month.

While the star was as beautiful as ever, she looked distinctly saggy in her ballgown without any underwear support.

Rita, tipped to become the 'British Rihanna', hit No1 earlier this year with R.I.P., featuring Tinie Tempah.

And she's taken to the celebrity lifestyle quickly, recently being linked romantically wiith Kim Kardashian's brother Rob.
