Give Beyonce a gold star in the "be prepared" category — or maybe she'd rather have a diamond.

The 25-year-old pop singer — and new star of the Emporio Armani Diamonds fragrance ad campaign — said she's learned to be photo ready at all times.

She carries three pairs of sunglasses (black, gold and brown) in her purse and a pair of nude-colored or gold shoes, in case she has to elevate her outfit at a moment's notice.

Many "Beyonce sightings" happen while she's shopping, but the superstar said she loves the pastime too much to give it up because of the risk of an unflattering photo.

"I enjoy shopping but I hate trying on clothes," she told The Associated Press in a recent interview.

One of her latest purchases: an 18-karat gold ring with a "hear-no-evil" monkey made of 5 carats' worth of yellow diamonds surrounded by white ones.

"I hear so many crazy things about myself that I'd rather not," she joked.
