Summer is over and all celebrities are reacting the same way: doing something to their hair. Charlize Theron cut them short as a bowl, Katherine Heigl became a brunette, and Tayna returned to descent with black hair. Britney Spears also made the decision to darken her hair as is the protocol now that we are approaching cold days.

In an Instagram post, the singer says she inspired her sister to step away from her blonde hair and darken it a bit.

Britney's boyfriend, Sam Asghari, likes them very much, at least judging by the comment she left below. "Beautiful blonde and brunette." As we were here, Sam said with full mouth that he would marry Britney. "Absolutely. It should do every couple. It's the whole purpose of a relationship - we're a family. If we get married, everyone will find out, "he told Entertainment Tonight.
