Meryl Streep and Don Gummer

 

Meryl Streep married sculptor Don Gummer back in 1978. When Streep's boyfriend at the time, (and her 'Deer Hunter' co-star) John Cazale passed away from lung cancer, a devastated Streep turned to a friend of her brother's - Gummer - for support.

Romance soon blossomed and the pair married within six months and have been together ever since.

If that's not a Hollywood love story, we don't know what is.
