Kelly Osbourne's representative has dismissed speculation the reality TV star is engaged to wed her boyfriend Matthew Mosshart.
The rock offspring sparked rumours she was taking her relationship with the vegan chef to the next level after she was snapped sporting a dazzling diamond on her ring finger on Sunday night (03Jun12) as she posed on the red carpet at the Miss Usa Competition she was hosting in Las Vegas, Nevada.
But a spokesperson for Osbourne has denied the claims, telling GossipCop.com, "She is not engaged."
Ozzy Osbourne's daughter, 27, began dating Mosshart after meeting him at supermodel Kate Moss' wedding last summer (11).
She was previously set to wed model Luke Worrall, but she dumped him in 2010 amid allegations of infidelity.
