In the immortal words of Aaliyah (RIP, girl), age ain't nothin' but a number. Throughout the years, a number of our favorite A-list celebrities have dated people more than 10 years their junior or senior. And in some cases, there's been more than a 20 or 30-year age difference!
We've rounded up our favorite celeb couples with huge age gaps, some of whom are still together and some of whom have called it quits (TomKat, #neverforget).
You may be surprised by a few of these high-profile duos, including Beyonce and Jay Z, The Walking Dead's Norman Reedus and Cecilia Singley, and two-time parents Megan Fox and Brian Austin Green. But the award for biggest age gap goes to Hugh Hefner and Crystal Harris. Bet you didn't see that one coming! But can you guess how many decades are between them?
Check out the Wetpaint video above to see if you're right, and tell us what you think of these mismatched couples in the comments below!
