Can you believe Kate Middleton and Kim Kardashian are allegedly due on the same day?!

On Thursday, the Duchess of Cambridge showed off her blooming baby bump at the Princess Cruise ship naming ceremony in Southampton, England.

The brunette beauty looked radiant wearing a black and white Dalmation print sleved dress, short black heels and a matching black hat.

This is reportedly Kate's last public outing before she is set to give birth in July.

You can barely tell that Middleton is 8-months along -- her thin face and lean legs have remained the same throughout her entire pregnancy! 

But the same can't be said for Kim, who's definitely been dealing with some serious feet, ankle and lip(?) swelling.
