Former Sudbury resident Nicole “Hoopz” Alexander confirmed to the Globe on Friday that she and her longtime boyfriend, retired Celtic Shaquille O’Neal, have called it quits. The two met in 2010 and lived in Sudbury together while Shaq played for the team. They left the local ’burbs when he retired, and have been living in Florida. Alexander was back in Boston with Shaq just a few weeks ago when he was called to the North Shore filming scenes for Adam Sandler’s local comedy sequel, “Grown Ups 2,” in which he plays a security guard. Alexander told us in 2011, shortly after moving to town, that she took to Sudbury because it reminded her of her hometown in suburban Michigan.
