The former reality TV star turned heads in her citrus-coloured frock and even opted for a brave plunging neckline that accentuated her bust, but still left her looking classy on the red carpet.
Her dress also featured a cinched in waist and short sleeves, so her figure was flattered to the fullest for the star-studded event in LA.
Given that her outfit was eye catching enough, Kelly kept her hair simple by tying it up into a chic beehive style and she accessorised with some cute triangle shaped earrings, a glittery pair of heels and of course, her sparkling engagement ring!
We also couldn't help noticing that her tiny clutch bag was rather unusual, as it appeared to be a clear perspex box with a safety pin design inside. Well, she does always like to make a statement.
Earlier this week, Kelly attended the Do Something Awards in Hollywood with another interesting handbag - this time one that had a cute smiley face design on it!
Kelly revealed that the fun orange accessory was in fact a vintage Hermes piece that she picked up in Paris years ago for her mum Sharon Osbourne, but she never got to use it.
The outspoken 28-year-old announced last month that she and her vegan chef boyfriend, Matthew Mosshart, are now engaged.
However, during an appearance on daytime TV show The Talk on Tuesday (30 July) Kelly admitted that the couple had been keeping their engagement a secret and Matthew actually popped the question back in December!
