Hollywood is no stranger to couples with big age differences. Names like the late Hugh Hefner and ex Crystal Harris, Charlie Chaplin and Oona O’Neill, and Doug Hutchison & Courtney Stodden are just some of them.

You have to wonder what it’s like getting to know someone older or younger.

Check out this list on star couples with massive age differences. They prove that age really is just a number.

Dick Van Dyke & Arlene Silver

Silver and Van Dyke started dating 2006, and got married in 2012. Dick Van Dyke was born in 1925 and he has 4 children born between 1948-58.
