Britney Spears is not known for her stellar style -- and this weekend's dirty ensemble was no exception.

Wearing a pair of soiled short shorts, the pop star spent some time with her sons Jayden and Preston in Calabasas, Calif. on Saturday.

Even if these shorts weren't so dirty -- we wouldn't love this ensemble (even if her body looks great in it!). But we love BritBrit regardless of what she's wearing!

Speaking of what she's wearing, the singer went for a hike on Sunday wearing a very skimpy ensemble.

The star posted a pic with the caption, "Nothing like hiking to refocus your energy. Can't wait to get back to Vegas this week!"

The "Lucky" singer has been on break from her Vegas residency at Planet Hollywood but is back on Wednesday.

Nothing like hiking to refocus your energy. Can't wait to get back to Vegas this week!
