10 Famous Actors You Never Knew Had Twins

We usually think of our favorite movie stars as one-of-a-kind, but this isn't always the case. You've seen them on TV, on the big screen, and maybe even center stage at a sold-out arena, but there may be someone you've been missing all along — their twin.
Some celebrity twins are extremely well-known, such as Mary-Kate and Ashley Olsen, Tia and Tamera Mowry, and Dylan and Cole Sprouse. In the case of those twins, they shared similar goals, which led to them becoming both household names.
But what happens when one twin desires the limelight while the other prefers a normal life? So you get a pair of less well-known celebrity twins. Some twins do not become famous because of a lack of opportunity or interest. People have no idea that many actors and models have fraternal or even identical twins. This is where we step in. Scroll down to check out some of Hollywood's most surprising celebrity twins you may never know.
