Surprisingly it was Leighton Meester’s first ever appearance on the “Tonight Show with Jay Leno” this week.

The “Country Strong” actress showed off her toned body wearing a simple but chic Versace Resort 2011 look.

Her checkered black and white mini dress with a pocket detail on the bust and a multi-coloured patterned pocket on the side, shows off her tiny waist.

She added Christian Louboutin Fastissima ankle boots and some gorgeous drop earrings to her look.

During the interview she talked about how she spent the holidays at home with her family in Florida, whilst Jay teased her about her recent steamy spread in Allure.

“Country Strong” hits theaters today in the US.
