Commencement scenes

Brown University may no longer have “Harry Potter’’ actress Emma Watson on its roster, but it can add actor Jack Nicholson to its list of affiliated celebs. The star of “The Departed’’ was given an honorary doctorate at the Rhode Island Ivy League school’s commencement yesterday. Media maven Arianna Huffington also received the honor… . Also earning a degree over the weekend was new UMass-Lowell graduate Charlene Colameta. Colameta, who is Red Sox prospect Ryan Westmoreland’s girlfriend, took time off from school last year when Westmoreland underwent brain surgery. Six months after he started rehab, the ballplayer convinced her to return to her studies. Colameta plans to start the EMC Corp. training program while Westmoreland continues rehab in Florida.
