This week, Dwayne "The Rock" Johnson once again shows off his ridiculously huge muscles. Does that look healthy to you? (We're going with scary.)
Jessica Alba takes to the shooting range to train for the "Sin City" sequel, while Katharine McPhee spends some time on set with an adorable furry friend!
Plus, Kristin Chenoweth is able to briefly return to the set of "The Good Wife" and looks great, Mayim Bialik shows off her still very-bandaged hand and Hilary Duff posts another super-sweet pic of baby Luca.
Check out the personal photos these celebs and more shared on Twitter this week!
