Jordin Sparks didn't need diamonds draping her body or a sequined gown to shine at the SAG Awards on Sunday night.

Instead, the 23-year-old Battlefield singer wore a simple Grecian-inspired draped gown that emphasized her backside.

The body-hugging purple dress showed off her curves, and the fact the singer appears to have kept off the 50 pounds she lost last year.

'Dick Van Dyke. Wow!' she wrote.

Sparks has been working on her third studio album, and is collaborating with singer John Legend on some of the songs.

She also starred in the film, Sparkle, which came out last year. During the filming of Sparkle, the singer had a dramatic weight loss of 50 pounds.
