From the red carpet of the hottest events to the city streets, stars were dressed to rock and shock this weekend in the best, worst & wackiest fashions – and Breaking Celebrity News has all the photos in our weekly feature.

Beyoncé put her baby bump on display at the Live at Roseland: The Elements of 4 screening in NYC, scoring herself the best look of the weekend. The mom-to-be wore a sensationally snug Roberto Cavalli gown, finishing the look off with Lorraine Schwartz bracelets.

Blake Lively is used to scoring slots on best dressed lists, but even the most fabulous fashionistas experience a blunder every now and then!  The hot blonde skated herself onto the worst dressed list at the Gossip Girl Celebrates 100 Episodes bash, wearing a fringed and embroidered Marchesa dress – that was better suited for the Ice Capades!

As for wacky, always eccentric Helena Bonham Carter sassed up the streets of London, wearing a peasant dress with construction boots.
