When a famous person gets pregnant, it's not just a matter of carrying a child for nine months and giving birth. No — there's maternity fashion, the publicity statement, and push presents to think about.

With Blac Chyna, Rob Kardashian's fiancé, due to give birth any day, it's been announced she bought herself a $400,000 Rolls Royce as congratulations for almost having a baby.

8. Jennifer Garner

After the birth of her daughter, Violet, Garner was given diamond ring by Ben Affleck—which she then dropped down a drain.

"He gave me this beautiful diamond ring and I was playing with it and... it fell off. And it fell under this ice maker in the house — he (Affleck) hasn't even heard of this yet — and... it fell into the drain under this ice maker," she told Live With Regis and Kelly.

"And the plumber had to come and dismantle the thing from under the house. And he found it. Ben hasn't even heard that."
