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 RadarOnline.com has all the photos in our weekly feature.

PHOTOS: The Best, Worst & Wackiest Fashions Of The Weekend

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.

Though Blake Lively has big Manolo Blahniks to fill, taking over Sarah Jessica Parker’s Sexy in the City status, the rising star is well on her way.

PHOTOS: Stars Hit The National Board Of Review Motion Pictures Gala

NYC’s current reigning 'It Girl' hit The National Board Of Review Motion Pictures Gala on Tuesday night, in absolutely smashing fashion. Wearing a to-die-for plum colored Marchesa lasercut sculpted sleeve cocktail dress with turquoise Lorraine Schwartz jewels (which were the perfect contrast with the deeply hued dress) and Burberry Prorsum ruched strap platforms, the Gossip Girl lived up to her style status.

Harry Brown (R)
Harry Brown is an elderly man who’s alone in the world, living out his later years in the shadow of rampant violence in a London project and playing chess with his best friend Leonard. Danger has crept into daily life, with wild, gun-toting teens ruling the streets and ineffectual detective work from the local cops. But when lawless locals murder Leonard, Harry has had enough. With nothing left to lose, he sets out to find Leonard’s killer and restore some order -- but not before waging a veritable war on his home turf. (Michael Caine [Harry Brown], Emily Mortimer [D.I. Alice Frampton])

Date Night (PG-13)
Leave it to Steve Carell to take a simple night out with his wife and unwittingly turn it into  a series of raucous events. In Date Night, he teams up with Tina Fey for a heavily promoted assortment of misadventures, thanks to a case of mistaken identity with the wrong (read: mafioso) crowd. While the movie features a comedic dream-team at its helm, even their brains and star-power couldn’t save every joke. The result is a mixed bag of funny and less funny, but with two of Hollywood’s top talents, even the tepid moments aren't so bad. (Steve Carell [Phil Foster], Tina Fey [Claire Foster], Mark Wahlberg [Holbrooke])

Death at a Funeral (R)
Put away the tissues, because this funeral is far from somber: For this family, a day of mourning their dad becomes a non-stop parade of over-the-top comedy, exposed secrets and reconciliation with the past (no matter how dirty the pictures, or how big the heartbreak). Sure, there are carnations, a casket and a few tears, but the proceedings unravel quickly when a lover from the past makes a surprise visit, a nutty uncle lets the potty humor rip, hot young things tempt the menfolk and a boyfriend hits the drugs (to be fair, he doesn’t mean to). With Chris Rock left to untangle the mess, this funeral can only get more wild, if not a bit heavy-handed. (Chris Rock [Aaron], Tracy Morgan [Norman], Martin Lawrence [Ryan], Zoe Saldana [Elaine])

Movie Review: Middle Men

Harry Brown (R)
On the surface, Harry Brown (Michael Caine) seems like a gentle old widower who lives alone in a suburban housing project in England, and spends time at the pub and taking walks. But when his best -- and only -- friend is killed by local thugs, Harry takes matters into his own hands. As he sets out on a quest for justice, his true ethos and mysterious past (not to mention his ease with guns) are revealed, as both lawless teens and an oblivious police force learn what real justice looks like (hint: it features blood and betrayal). (Michael Caine [Harry Brown], Emily Mortimer [Alice Frampton])

Movie Review:  The Other Guys

My Name Is Khan (PG-13)
How far would you go for love? Obviously not very, compared to Rizwan Khan. An Indian-born Muslim with Asperger’s syndrome (a form of autism), this indie flick with Bollywood stars charts his journey from Mumbai to San Francisco,and across the U.S. on a mission to win back his true love. Everything had been going great until 9/11, when Muslims in America became suspect, and tragedy struck at home. Rizwan’s beautiful Mandira takes off, but her departure doesn’t hold him back: Determined to clear his name and win her over once again, Rizwan sets out to set the record straight -- and stand up for love. (Shahrukh Khan [Rizwan Khan], Kajol [Mandira])

Movie Review : Dinner For Schmucks

The Joneses (R)
The American dream gets turned on its head in The Joneses, in which a faux family uses their manufactured perfection to sell everything from golf irons to catering services.  As sales skyrocket and their popularity soars, things start to turn sour as their real-life feelings start to get in the way of their professional success. It’s a relief that a make-believe family really can’t be that perfect -- but as the Joneses discover their own realities, it’s unnerving what they reveal about ours. (Demi Moore [Kate Jones], David Duchovny [Steve Jones])
