Every once and a while something comes around that grabs the attention of Hollywood's hottest A-listers. What is it this time?

Frozen yogurt. Yup, Hollywood is bringing frozen yogurt back (yay). Not one, but two hot spots are attracting quite the following of folks looking for a sweet treat that is actually good for you and not jam packed with calories.

Berri Good Kosher Frozen Yogurt is rich in calcium, but there is so much more. It also claims to "boost immune system, prevents acne and builds clear skin, builds strong bones and teeth, prevents bacteria in intestine and promotes good digestive system." Berri Good is not only Kosher, but also eco-friendly. Among others, Leonardo DiCaprio and girlfriend Bar Rafaeli are serious Berri Good followers. Berri Good says that it's, "Probably the best tasting non fat frozen yogurt in this world." Probably, if Leo eats it, I bet it's more than probably the best.

One ounce of the other yogurt in Tinseltown, pinkberry, has only 25 calories, 0 grams of fat, 35 mg of sodium and 6 grams of carbs. Some of the locations are known for their hour long lines -- Paris Hilton, Hilary Duff, David Hasselhoff and many others have been spotted picking up some yogurt from here. Pinkberry says, "Pinkberry is yogurt, pure and simple."

Anyone tried either? Which do you prefer?
