After confirming her pregnancy in November, Dwayne "The Rock" Johnson's longtime girlfriend, Lauren Hashian, has been prepping for the arrival of their baby girl. But the 31-year-old is hopeful that her daughter doesn't inherit her famous father's large stature!

"Like Big Daddy says – Couldn't be prouder of all the kickass women she's going to have around her! And Men of course ;).. #LetsJustHopeBigDaddyDoesnt=20lbBaby," Lauren hilariously wrote on Instagram.
