Congrats to Boston Celtics owner Wyc Grousbeck on his engagement. We’re told the C’s CEO is engaged to Emilia Fazzalari, a New York businesswoman whose resume includes stints at Moody’s, Bloomberg L.P., and Poten & Partners. The couple sat courtside at Friday’s Celtics game, and Fazzalari’s ring finger was adorned with an impressive rock. The pair were together again Saturday night at a holiday party in Brookline hosted by Bain Capital’s Paul Edgerley and his wife, Sandy, and they shared the happy news with guests. We’re told the couple is getting married in April. Grousbeck and his ex-wife Corinne have two children, and Fazzalari also has two children.
