Today's Blind Items - Strange Hookups - Old Hollywood Edition - Mr. X

1930s: Which permanent A+ list actress/multiple Oscar winner-nominee whose sexuality still remains a mystery (doing a bit of research my best guess is that she was bisexual/bi-curious) slept with the iconic character actress/widow of a famous Broadway mogul who was playing her mother in her debut film. 

1940s: the frequent costar of the pint sized actor, the permanent A+ list actress/singer who everyone knows, had a one night fling with an unusual-looking permanent A list actor best known for film noirs. 

1950s: two permanent A+ listers, who played parent and child in two movies that were remade in the 1990s. 

1960s: the spawn of the actress/singer in BI #2 and the foreign born front man of one of the greatest hard rock groups ever, who has had an eclectic solo career.
