From the red carpet of one of this summer's hottest movie premieres to the streets of NYC, Hollywood¹s hottest stars were dressed to rock and shock on Monday ­ and Breaking Celebrity News has all the photos.

Emma Watson continued her spellbinding Harry Potter and the Deathly Hallows Part 2 style streak in NYC.  First, the 21-year-old Brit made an appearance on the Late Show with David Letterman, dazzling in a Balmain mini and Christian Louboutin wedges.  Later in the day, she changed into a Bottega Veneta corseted gown, Giuseppe Zanotti platforms and Lorraine Schwartz jewels to walk the red carpet at the premiere.

LeAnn Rimes experienced a cutout catastrophe at the GBK ESPY Awards pre-party.  The super skinny star, who loves tweeting bikini pics of herself, wore a body-baring white mini, which reminded us a little too much of Julia Roberts' Pretty Woman number!

Sarah Jessica Parker looked Harry Potter haute in Oscar de la Renta, while Lady Gaga wore another arrest worthy ensemble, dressing up like a sexy cop for the second day in a row.
