They Dated?! Golden Globes Edition

Before we see the nominees and their plus-ones at Sunday's 70th Annual Golden Globe Awards, we're looking back at the past dates of the star-studded event.

PICS: Golden Globes Presenters

If the Globes had an award for unpredictability, it might be a toss-up between George Clooney and Bradley Cooper.

In 1997 and '98, Clooney showed up with then-girlfriend Celine Belitran, but for his next four Globes appearances he walked the red carpet alone. Then in 2010, he escorted Elizabetta Canalis, but last year he had Stacy Keibler on his arm.

Cooper has also kept us guessing. In 2006, he was snapped with then-girlfriend Jennifer Esposito, but in 2010 he turned the awards show into a boys' night out with the cast of The Hangover.
