Unlike someone looking for a sugar daddy/mommy, when celebrities get into relationships with older people, there is usually a different reason. It could be career moves; maybe it’s a midlife crisis, it can be compatibility and even love. The one thing they’re always mindful of is the age gap.

For that, there’s an equation that, while not scientifically proven, still does a good job. It’s called the half your age plus seven rule, where the older person in the equation halves their age and adds seven, if the younger person is the same age or older, good stuff. If not, be prepared to be called a cradle snatcher.

Nick Jonas & Priyanka Chopra – 11 Years

Sadly, for all those swooning teenagers who became swooning young adults thinking they’re old enough to marry Nick Jonas now, he’s spoken for. He is married to Priyanka Chopra, the Bollywood actress who has made Hollywood her playground with roles in films like We Can Be Heroes.

She is 11 years older than him, meaning that our man Jonas is into older women, and again, if you were his age or younger, that means you’re definitely not his type. Not that Chopra looks 11-years older than him, she doesn’t look much older than him anyway. Chopra has another Hollywood role, not the horizon in the much-anticipated Matrix 4.
