Celeb Love: 44 Celebrities You Didn't Know Were Friends

Ah, unlikely celebrity friendships. You are what makes the world go round. Nothing makes us happier than when two celebs who should be polar opposites come together in peace and love. Improbable celebrity duos running out and about in the world fill us with joy, and we hope they do for you, too. Sure, soul mates like Ian McKellen and Patrick Stewart, with their precious bowler hats and selfies, fill us with love and hope for a bright future, but there's just something magical about two people coming together from completely different ends of the celeb spectrum. What will you get when Channing Tatum and Jonah Hill get silly, or when Will Ferrell and John C. Reilly decide to smooch it up courtside? Pure wonderfulness, that’s what. And there are no words to describe the glee that takes us over when 50 Cent and Bette Midler decide to champion a new Restoration Project park. Frankly, if we could program the site to take care of itself, we'd be out there planting trees along side Bette and 50.

To that end, we've rounded up our absolutely favorite celebrity friendships that you weren't aware of (sneaky celebs, flying under the radar).

From Snoop and Martha to LiLo and Lady Gaga, we've got all the fabulously strange celebrity friendships you need to know about. These are the celebrity duos that will fill your heart with love at the mere thought of them. Just knowing that they are out there, living and loving, is enough to thaw even the iciest heart.
