Did everyone else know that Warren Beatty and Shirley MacLaine are siblings?

Is this just common knowledge and I missed it all these years? Not super-relevant I guess but still pretty mind-blowing as an 80s/90s child.

Yes, forever. She was born Shirley McLean Beaty in Virginia in 1934. Named for Shirley Temple. Younger brother Henry Warren Beaty was born 1937, also in Virginia. Shirley changed McLean to MacLaine and dropped the Beaty. Warren dropped Henry and changed Beaty to Beatty. Both terrific actors. My personal favorite roles: Shirley in Being There, Warren in Heaven Can Wait.
