Bradley Cooper was hard to miss as he dined with Rachel McAdams, Emma Stone, and a few other folks at the Bristol Lounge at the Four Seasons the other night. Cooper is in town shooting a movie with director David O. Russell. On her way into the hotel, Stone (right) stopped to pose for a picture with Tewksbury’s Mike Giannattasio, who’s made a habit of getting his photo taken with famous people. . . . That was “Risky Business” actress Rebecca De Mornay standing outside Aquitaine Monday morning. Leonard Cohen’s former girlfriend was at the South End restaurant shooting a scene for NBC’s “Hatfields & McCoys” pilot. . . . Comcast SportsNet’s Jessica Moran celebrated her birthday over the weekend, having dinner and drinks at Empire with NESN’s Jenny Dell and MLB reporter Jen Royle. . . . If eating granola qualifies as brunch, “One Tree Hill” star Sophia Bush had brunch at Sonsie over the weekend, and Bruins wing Tyler Seguin was also in after the team returned from Toronto.
