Christie Brinkley is always a baddie in a bikini. Brinkley, 71, showed off her famous curves in a two-piece while taking a selfie in front of a homemade, shell-adorned mirror. In the pic, which she shared via Instagram on Thursday, January 15, she wore a black top featuring triangle cups and halter straps. Brinkley styled the piece with high-waisted, boy-short bottoms. Brinkley went makeup-free in the pics and showed off her natural beauty. Her blonde hair was parted to the side and styled in a soft blowout.
