From the MuchMusic Video Awards in Canada to biggest Sin City soirees, Hollywood’s hottest stars were dressed to rock and shock over the weekend in the best, worst & wackiest fashions and Breaking Celebrity News has all the photos in our weekly feature.

Selena Gomez brought her steamy style north of the border for the Canadian awards show, rocking a super chic and sexy Burberry Prorsum mini on the red carpet. The Disney diva paired the tiny little thang with bright purple Giuseppe Zanotti peep-toes, dominating the red carpet. Also at the show, Avril Lavigne wore another Sk*er girl outfit (blah!) while Lady Gaga upped the wacky factor wearing one Versace outfit after another.
