Caught in the Act!

Nicole Richie and Drew Barrymore

See where the stars (Nicole! Drew! George!) have been seen and heard.

• Nicole Richie and a female pal, buying groceries at a Ralphs store in Malibu. The pair then took a stroll to the beach, where they made a dash for the surf. "They were really enjoying themselves," says an onlooker. "They ran through the water, having fun."

• Drew Barrymore, dining with two friends at West Hollywood eatery Il Sole on Thursday. On the table: risotto with porcini mushrooms, onions and carrots. "They had an excellent evening," says an observer. "They chuckled all night."

• Adrianne Curry and Christopher Knight, renewing their vows at Pure Nightclub at Caesars Palace in Las Vegas. An Elvis impersonator officiated at the faux ceremony, which took place only 81 days after the couple tied the knot in her hometown, Joliet, Ill. Among their Elvis-themed vows: "I promise to love you tender, baby, and never leave you with a suspicious mind." Later, they celebrated Curry's 24th birthday with a bash at the club.

• Natalie Portman, attending a private dinner hosted by violinist Joshua Bell at New York City's SushiSamba Park. The actress was accompanied by her parents and feasted on a special vegetarian menu prepared especially for her, which included portabello mushroom-and-tofu "seviche" along with shaved asparagus and mango salad.
