Kelly Osbourne and Luke Worrall might have only been dating for six months, but they seem like one of the happiest couples around – so perhaps we shouldn’t be surprised that they’re engaged already! Kelly and 19-year-old model Luke changed their Facebook relationship status to “engaged” over the weekend, and they’ve since been flooded with wall posts from friends and family congratulating them. Kelly’s actually been wearing a ring on her engagement finger for a couple of months, but it seems they’re now ready to go public with their news. Congratulations Kelly and Luke!
