Actress stuns on red carpet - 18th Annual ELLE Women in Hollywood Tribute

Michelle Pfeiffer has been MIA for the majority of the year, but she made a triumphant return at Monday evening's 18th Annual ELLE Women in Hollywood Tribute. The 53-year-old actress -- who'll next be seen in Garry Marshall's "New Year's Eve" -- turned heads in a chic Alexander McQueen frock and massive McQueen belt. A diamond-encrusted cuff, gold clutch, and black platform peep-toes completed her flawless look.

Following in Pfeiffer's footsteps was the equally glamorous Evan Rachel Wood, who nearly stole the spotlight upon arriving at the Four Seasons Hotel in Beverly Hills, California, in a sleeveless Alessandra Rich gown, Giuseppe Zanotti heels, and statement necklace

Our other favorite fashionista at this year's ELLE soiree was Jayma Mays. The "Glee" cutie perfectly accentuated her fabulous head of red by donning a bright blue Catherine Malandrino gown, which featured cascading ruffles.

Also spotted in a bold hue ... Nicole Richie, who delivered a breath of fresh air at the 2011 Environmental Media Awards in a super cute chiffon dress, courtesy of Keepsake. The former "Simple Life" star's accessories included a few bracelets, a $225 House of Harlow clutch, and Christian Louboutin "Luxura" pumps

Catherine Zeta-Jones was the epitome of elegance at Sony's 6th Annual "A Fine Romance" event. The screen siren sported diamond baubles and an intricate Elie Saab stunner that hugged her curves in all the right places

Demi Moore looked ferocious in an animal print Zac Posen dress and studded Brian Atwood pumps at the New York City premiere of her upcoming thriller, "Margin Call." Ashton, eat your heart out!

Ciara is either hit or miss when it comes to red carpet fashion, but the R&B songstress knocked one out of the park at a recent Africa Outreach charity event. What do you think of her blush-colored Valentino blouse and leather skirt? Hot or not?

Lucy Liu is a fashion risk-taker, and that's why team omg! loves her! Check out the $4,000 floral Giambattista Valli dress she rocked to the launch party for her new book, Seventy Two. You may think the shoulder pads and aqua clutch are a bit much, but we think they're just right. 

Naomi Campbell and her billionaire boyfriend, Vladislav Doronin, were honored at Tuesday's Angel Ball for raising over $7 million for Haiti relief. Doronin looked incredibly handsome in a sleek suit, while Campbell killed it in head-to-toe McQueen, including a harness belt.

I'm not a huge Taylor Swift fan, but I have to give her major props for the look she presented at the unveiling of her first fragrance. The country star bested expectations in a lovely Tracy Reese cocktail frock, which featured sparkly black stripes and a nude underlay, black Miu Miu peep-toes, and a loose updo

Hayden Panettiere is very short, so it's difficult for her to find outfits that don't make her appear too tiny. She succeeded in selecting this bedazzled Jenny Packham mini -- and Louboutin peep-toes -- for the Los Angeles premiere of "Fireflies in the Garden." 

And last but not least ... George Clooney and his new gal pal, Stacy Keibler, at the New York Film Festival premiere of "The Descendants." Are you fond of the new power couple? More importantly, are you fond of her revealing Versace gown?
