Britney Spears was back in workout mode as she swung by a LA gym on Monday afternoon, and afterwards she treated herself to a spa session. While things have remained rather innocent these days for Brit, she did cause quite a stir by coming out of the locker room wearing only a towel! It was good that she got in some relaxation time while she could, because earlier today she was back on the set of How I Met Your Mother to begin rehearsals for her upcoming appearance. Now we just have to wait two long weeks until we can see Britney’s big return on May 12!
