Zoe Saldana was back on her grind last evening at the 2011 Hollywood Style Awards held at Smashbox Studios Nov 13 in Los Angeles.

The 33-yr-old “Colombiana” actress was on hand to present the ‘Hair Stylist of the Year’ award to Mara Roszak during the event to honor the industry’s top make-up artists, stylists and designers.

The sighting comes less than 48hrs after Zoe and her longtime beau Keith Britton, 35, “amicably separated after 11 years,” her rep confirms in a statement.

Serena Williams attended the event as did Eva Longoria, Selma Blair, Mandy Moore, who presented awards.

Get this, Khloe Kardashian was on hand to honor her little sisters Kylie and Kendall Jenner with the ‘Stylish Sisters’ award.
