beyonce jay z jay-z concert perform downtown la dtla staples center Matthew Mosshart Kelly Osbourne

Kelly Osbourne and fiance Matthew Mosshart attended the Beyonce concert at the Staples Center on Tuesday night, and the Fashion Police host showed off her curves in a pair of plaid pants and a black leather jacket.

While her weight has fluctuated a bit over the years, we admire Ozzy's daughter for being confident about her body no matter what. Back in 2012 Kelly did an interview with Glamour and revealed how she's embraced her imperfections and learned to love the skin she's in.

"No, we are not all Gisele Bundchen; were not all Beyonce," she said. "But I can tell you even the most beautiful girls in the world have felt insecure. And just seeing the pressure my friends Kim Kardashian and Kate Moss are under makes me never want to even be the prettiest woman in the room."

And yes, this was also the interview where she famously dished on her feud with Christina Aguilera. "She called me fat for years," Kelly said. "One night on Fashion Police I said, 'F*ck you. Now youre fat too.' I didnt say I wasnt fat. I said, 'Now you know how it feels.'" Wonder how Xtina feels about that now that she's slimmed down to the size she was in the early 2000s?
