• High School Musical costars and real-life couple Zac Efron and Vanessa Hudgens, visiting Pinkberry in Studio City, Calif. for a cold treat. The pair went incognito in hoodies and sunglasses, but they sure acted super cuddly, an onlooker says. The pair held hands while ordering their yogurts.

• Jason Priestley, indulging in some chocolate decadence with wife Naomi Lowde. The pair ate their dessert at Toluca Lake wine bar Eight-18, and they met up with actor Max Martini. Along with the chocolate cake, the duo sipped Moscato d'Asti semi-sparkling dessert wine.

• Harrison Ford, taking a break from shooting the fourth installment of Indiana Jones to share a romantic candlelit supper with Calista Flockhart. The pair dined at Zinc on Chapel Street in New Haven, Conn. where Ford has been filming. According to a source, the two "seemed really happy."

• Beyoncé Knowles and beau Jay-Z, rolling up in a four-car caravan of black Cadillac Escalades at the seven-acre Stereo House property in Watermill, N.Y. "It looked like the president was arriving," an onlooker tells us of their grandiose entrance. The musical duo was on hand for business associate John Meneilly's p.i.n.k. vodka-sponsored birthday party, which included a poolside dinner for 30 guests. At the soiree, Jay-Z played ping-pong, and guests dined on caviar, lobster and steak. The birthday guy was treated to a four-layer ice cream cake and, of course, the requisite rendition of "Happy Birthday."

• Ellen DeGeneres, dining al fresco with girlfriend Portia de Rossi at popular Laurel Canyon eatery Pace. The couple ate a low-key meal at a secluded table on the restaurant's front patio.
