What are you going to reward your wife with when she gives birth? You'll have to help out with the baby, that's for sure, and you'll have to make sure your wife has everything she needs. But maybe you need to give her something extra, since she went through those nine months carrying your child, and had to go through labour at the end.

You'll probably buy her something nice; a piece of jewelery perhaps, or plan a short holiday for you and her, or buy her a branded bag. Fortunately for you, it wouldn't have to cost as much as what these celebrities are gifting their wives or girlfriends as push presents. Here's what these celeb mommies got:

Beyonce

When Blue Ivy was born, Jay-Z gave her an extra-large blue Tanzanite ring as a push present.


Jennifer Lopez

Marc Anthony gave her a $2.8 million canary-yellow diamond ring and custom diamond earrings engraved with their children's initials, after Jennifer Lopez gave birth to twins Emme and Max.


Jessica Simpson

Mariah Carey

Nick Cannon presented her with a diamond-encrusted nameplate necklace featuring their kids' names. "It says 'Moroccan and Monroe' in pink-and-white diamonds. My wife has so much jewelry, so I've got be really creative when I give gifts," he said.


Kim Kardashian

Baby daddy Kanye West gave her a £500,000 diamond ring after giving birth to North West. She also got a Burger King franchise.
