What a difference a few hours makes! Melissa McCarthy went from barefaced and blah Saturday afternoon on her way to an exercise class, to brilliantly red carpet ready last night at the Producers Guild Awards.

The Mike & Molly and Bridesmaids star was first spotted in plain black sweats on her way to Pilates class near her Toluca Lake, Calif. home. Her hair was pulled back with a black headband and her face was free of make-up.

Fast forward to the Beverly Hilton Hotel and the Producers Guild Awards where Melissa was a presenter.

McCarthy pulled out the glam factor in a stylish black pants suit with pink silk blouse.  Her hair fell in sophisticated curls.  Her smoky eye make-up and chandelier earrings completed the look. Wow!

Look out Angelina!

Brad Pitt and Angelina Jolie didn’t take home away statuettes for their work Saturday night, but they could have been easily won the award for Most Glamorous Couple at the 2012 Producers Guild Awards.

Angelina looked happier than ever.  Her long hair was styled into soft curls, and she wore a stunning Michael Kors black wool crepe column gown with lace detail.

Brad Pitt at her side completed the ensemble, and the couple laughed, smiled, held hands and had their arms around each other the entire event.

On the awards side of things, The Artist won for Best Feature Film – Brad’s Moneyball was one of the nominees.

Incidentally, the last four PGA best film winners have gone on to win Best Picture at the Academy Awards.
