First Sandra Bullock and Heather Graham wowed in leather and now actresses Naomi Watts and Samantha Barks are rocking the new summer 2013 style trend.

Watts hit up the premiere of boyfriend Liev Schreiber's new TV series "Ray Donovan" this week wearing a very sexy Alexander McQueen leather dress which featured a teardrop neckline and a pleated skirt. The 44-year-old Aussie, who plays the late Princess Diana in the upcoming biopic "Diana", clearly knew she was the star of the red carpet judging by her smug grin.

But Naomi's leather look isn't unique! "Les Miserables" actress Samantha Barks also stepped out this week in a revealing leather dress with side cutouts and not one but two thigh-high slits!

Can we thank Jennifer Aniston for this (literally) hot summer trend or will Justin Bieber take the credit?
