9. Emily Blunt And Stanley Tucci
Relation: Sister-In-Law Forget about dating websites, nightclubs and work relationships, the only matchmaking service you need if you're famous, it seems, is a brother or sister. British actor Emily Blunt is sister-in-law to Stanley Tucci through the marriage of her sister to the Hollywood actor. Not only that, but Blunt herself was the one to introduce the two former singletons. Unlike her famous sister, Felicity Blunt is a literary agent, so any chance that she might have met Tucci without the intervention of her big sister is practically zero. In fact, we're surprised that that the film industry hasn't created some form of special dating service where the public can date their idols yet. Quick, someone get down to the patent office!
