PICS: Beyonce Debuts Another Hairstyle

The 31-year-old Mrs.Carter debuted her latest look while out to lunch in Miami with hubby 

Jay Z and the couple's daughter Blue Ivy.

The singer's "Beyhive" may be going through some changes, but the star exuded her usual

fabulousness rocking denim short-shorts, a loose "Name Brand" tank, a pair of aviator shades 

and a gold headband.
