Listen to Beyonce on iHeartRadio

(Yahoo!) - If it’s true that blondes have more fun, then Beyonce must be having a time of her life!

In a new ad posted on her Facebook page Tuesday for her upcoming “The Mrs. Carter Show World Tour,” prominently sponsored by Pepsi (for which the superstar is their $100 million girl!), Beyonce offers up her best Marilyn Monroe impression, with four provocative poses showcasing her new hair color.

In the new images, Mrs. Carter sports tiny Daisy Duke shorts and a tight white turtleneck sweater. While she’s worn blond highlights in her hair for a long time, she’s never quite showcased this drastic shade. It’s unclear though, if she’s simply wearing a wig … or perhaps, just has in extensions.

So, what do you think of Beyonce’s predilection for a brighter coif?
