• Lindsay Lohan and John Mayer were both hanging out with Samantha Ronson, who was deejaying at New York nightspot Butter. Mayer arrived first with his male posse in tow, and the singer scoped out the scene and stopped to flirt with female revelers. He also greeted Ronson at his table, though she soon headed over to the deejay booth. Then Lohan arrived and started chatting up Mayer. While Lohan was definitely there to see Ronson, according to an onlooker the two didn't really interact much, though they were at the same table all night. "You could tell they were there together and both talking to John Mayer," the onlooker says. "They all stayed at the same time talking until past 3 a.m."

• Back from Miami, Justin Long and Drew Barrymore had a dinner date at Morimoto in New York with Jimmy Fallon and a friend. The group shared sushi, sashimi and sake and good conversation. Long also picked up the tab and left a 25% tip, according to a source.

• Apparently Celine Dion is a basketball fan! The singer cheered on the Miami Heat along with her husband René Angélil and their 8-year-old son René Charles as the team faced off against the Boston Celtics at the American Airlines Arena. "They had a great time and were nice and friendly to everyone," a source tells PEOPLE. "The whole family looked like they love basketball!" Unfortunately for Dion, though, the hometeam lost to the Celtics 92-85 in the end.

• Brothers star Natalie Portman, taking home cookbooks by star chef José Andrés after eating at his L.A. restaurant The Bazaar by José Andrés. She and her party sampled a number of the dishes during their meal and, a source says, "she was in a great mood."

• Abigail Breslin, enjoying a family dinner with her mother and some friends at New York's Wildwood Barbeque. The group sat down to a full rack of baby back ribs, a pulled brisket sandwich, a pulled pork sandwich, brisket nachos and jalepeño bottle caps.
