Bradley Cooper & Irina Shayk: She's My Wednesday Supermodel

Absolutely NOBODY's got it better than Bradley Cooper, who's strolling around Paris with Irina Shayk ... just a few days after kicking it with Naomi Campbell.

Bradley was back arm-in-arm with his 30-year-old supermodel chick Wednesday morning, looking like they never missed a beat. It's the first time they've been spotted together in about a month.

Of course, over the weekend he was trending a bit older -- doing breakfast with 45-year-old Naomi.

That kinda range wins awards. And ass.

However -- wet blanket time ... sources close to Naomi tell us she and Bradley are just good friends, have been for years. She was in L.A. for Oscar parties, and they grabbed a quick bite to catch up.
