Catherine O'Hara remains one of Hollywood's most beloved stars, displaying a range that stretches from doting mom in the Home Alone franchise to kooky thespian in Schitt's Creek.

The actress, who turned 71 today, may be one of the biggest personalities on screen, but as for her life away from the cameras, she maintains a more private existence.

The Emmy and Golden Globe winner has been a wife to Bo Welch for over three decades, and the couple share two sons, Matthew and Luke.

The Second City star isn't the only famous one in her family. Since 1992, Catherine has been married to Robert W. "Bo" Welch III.

The pair met on the set of the original Beetlejuice in 1988 and began dating soon after, eventually tying the knot a few years later and welcoming two sons.

Bo is also a Hollywood man, although most of his work happens behind the scenes. He is an extremely accomplished production designer, art director, as well as a film and TV director.

He has made a name for himself with the often surrealist blend of horror and camp in his creations, most notably with Tim Burton and Barry Sonnenfeld, including credits like the Men in Black franchise, the 1985 version of The Color Purple, Beetlejuice, Edward Scissorhands, Batman Returns, The Birdcage and many more.
