• It was like two exes passing in the daylight: Kirsten Dunst, wearing a little black sundress and sunglasses as she sat down for lunch with a male companion at Joan's on Third in Los Angeles – not long after former beau Jake Gyllenhaal was spotted leaving the gourmet market with a coffee to go.

• A cowboy hat-wearing Kevin Costner with wife Christine and baby Cayden Wyatt, dining on the patio at the Inn of the Anasazi on Washington St. in Santa Fe, N.M. The proud dad held his baby while the family enjoyed lunch. "He was showing off the baby to a number of interested bystanders. It was very cute," an onlooker tells us.

• Hilary Duff, with hockey player boyfriend Mike Comrie, enjoying a quiet brunch at Sushi Samba Park in New York. The couple arrived in the afternoon and tucked into a casual meal of sushi and sashimi and washed it down with water. Comrie, ever the gentleman, picked up the check.

• Carmen Electra, rocking out to the sounds of Aerosmith and Joan Jett and the Black Hearts at the Borgata Hotel Casino & Spa in Atlantic City, N.J.

• Celebrating their new show, NBC's Chuck, Zachary Levi and Sarah Lancaster dined with the rest of the cast and crew at Social House in Las Vegas. After dinner, the group headed over to PURE Nightclub, where they partied in the VIP area. "It's not like NBC said, 'Here, we want to make you a big star' but it's pretty surreal. I'm very grateful," says Levi, who was later spotted smoking and rocking out on the dance floor.

• Paris Hilton, with new guy Alex Vaggo, dining on a tuna tartar roll and crab corn dogs while at New York's Stanton Social, before meeting up with America's Next Top Model winner CariDee English and her boyfriend at Runway. There, the heiress danced on the banquettes to her song "Stars Are Blind," and a mystery guest sent over seven bottles of champagne.
