Everyone has a different definition of “Sunday Best.”

Britney Spears and boyfriend David Lucado were photographed attending religious services on Sunday in Thousand Oaks, Calif., in some interesting outfits.

Wearing thigh-high boots and a tight gray-and-black dress, Spears, 31, sported messy hair as she held hands with Lucado, who wore a vest, tie and jeans.

In March, Spears was photographed attending Easter services in Amite, La., with her mother and son.

Most recently, Spears and Lucado attended the premiere of The Smurfs 2 in Westwood, Calif., with the singer’s sons – who star alongside their mother in the music video for “Ooh La La.”
