Kelly Osbourne shows off her post-breakup body while partying at Haze Nightclub in Las Vegas ... and we gotta say, girlfriend is looking fab!

Wearing a short, form-fitting blue dress, Miss Osbourne showed that sometimes a breakup does a body good.

Earlier this week, Kelly and fiance Luke Worrall split over reports that Luke was caught cheating. Immediately after the news got out, she expressed her candid feelings through her Twitter page.
