Rihanna in Stella McCartney - 2012 Time 100 Gala Performance

Rihanna performed at this year's Time 100 gala.

She took to the stage in a Stella McCartney Pre-Fall 2012 ensemble.

The look consisted of a gold strapless top with an oversized red bow on the bodice, and silvrecropped pants.  It was sweet and simple - very appropriate for the event.

Rihanna in Marchesa - 2012 Time 100 Gala

Rihanna ditched her daring fashion sensibility at this year's Time 100 Gala.

The singer wore a sweet pink Marchesa Resort 2012 dress.  The strapless silk dress had a draped bodice and a flared skirt looked lovely on her.

Newly jet black hair was worn in waves, and the red lipstick added another colour to her look with Christian Louboutin pumps completing the look.

The Time 100 Party

Blake Lively, Anna Kendrick and Kerry Washington were at Time magazine's 100 Most Influential People's list bash.

Blake's hair! It's red! She channelled Ariel in this aqua, draped Zuhair Murad gown, worn with mermaid waves and a big smile! It's a nice look but I'm still not quite used to her hair being not blonde.

Anna Kendrick chose a plunge neck LBD by Zac Posen, she manages to pull the bold look off and the dress is just jazzy enough for a party without being OTT.

Kerry Washington looked great in a silk, purple hued Malandrino that had a subtle watercolour print on it. I like the simple hair, make up and nude Jimmy Choos.
