Sofia Coppola & Thomas Mars of Phoenix
Even though they're not married Sofia and Thomas still fit the bill of significant others who work together–especially since they just had their second child. Thomas and his band Phoenix have collaborated with Sofia (once again) on her latest film that everyone is excited about, Somewhere. I think working together and doing a creative collaboration might even be a bit tougher. So kudos to these two.
