FIRST PHOTOS - Britney Spears Debuts New Brunette Look

Uhhh sorry BritBrit, but we are not liking the new look!

Pop star Britney Spears showed off her new brunette hairstyle while making a post-gym stop at Michael's craft store in Calabasas on Thursday. And we are a little baffled by the normally blonde star's color choice!

Dressed down in her usual off-duty gear, Britney was looking anything but an A-lister for her errand-filled afternoon.

Here are some hair commandments that we really don't think should be messed with: If your name ends in "Kardashian," thou shalt forever be brunette (stop with this ombre and blonde madness, it does your family no justice!). Secondly: if you are a pop icon whose name is Britney Spears, thou shalt be a blonde.

There is just something off kilter with the world when they flip flop their signature hair colors -- and we just don't like it.

This is the first time we've gotten a good look at the reddish brown mane, however we did see a pic earlier in the week of the darker style. On Tuesday, friend Nicole Richie Instagramed a pic of herself and the newly brunette singer while on stage at Brit's show in Las Vegas, but this is the first time we've seen her out and about with the new 'do. The 32-year-old reality star-turned fashion designer was seen smiling as the "Toxic" singer pulled her on stage for a sexed-up performance of "Freak Show."
