• Jennifer Lopez and Marc Anthony, sharing a late-night dinner à deux at Cecconi’s in West Hollywood. For their date night, the two grabbed a back corner table outside, wine for him (and a drink for her) and seemed really into just being with each other. “They were totally cute,” an onlooker tells us. “Really deep in conversation, and they seemed to be having a good time.” Also dining at the Italian restaurant that night: Lindsay Lohan.

• Adam Lambert, partying in a cabana on the rooftop of the Hotel Gansevoort in New York City. The American Idol runner-up – who wore jeans and a T-shirt – sipped Fiji water and snapped photos and signed autographs for fans as he hung out with friends. “He was extremely gracious,” a source says.

• Foregoing the traditional Memorial Day barbeque for a different sort of comfort food, Miley Cyrus ordered fried macaroni and cheese at The Cheesecake Factory at the Sherman Oaks Galleria in Sherman Oaks, Calif. There with beau Justin Gaston, the teen star acted ultra low-key during her 5 p.m. meal – but took to Twitter to rave about her early dinner. “Fried mac and cheese balls are the bestest thing ever invented,” she tweeted.

• Jamie Kennedy, celebrating his 39th birthday at LAVO in Las Vegas with girlfriend Jennifer Love Hewitt. The couple held hands throughout their romantic dinner, then headed to the upstairs nightclub where they grabbed a VIP table on the dancefloor. And it was a couples night at LAVO: Kevin Federline also dined at the Italian restaurant with Victoria Prince before venturing to the club, too.

• Vince Vaughn, relaxing with fiancée Kyla Weber at the Mii Amo Spa in Sedona, Ariz. The actor cuddled and read magazines with Weber while waiting for their spa treatments, a guest tells us. During their stay, the couple also lunched poolside with Vaughn’s parents.
