In the snapshot, Vergara -- rocking a tiny black string bikini -- is seen looking fierce as she soaks in the crystal blue waters of Miami and poses for the camera.

Vergara is no stranger to strutting her stuff online. The actress recently shared several more throwback bikini snaps in late January — donning a white bikini top, a diamond choker and dangling silver earrings.

In late December, Vergara broke Instagram once more when she shared a picture of herself lifting up a small dog while lying out on a lounge chair and soaking up some sun.

Her long legs and flat tummy were on display as she relaxed in a dark-colored suit with a large floppy visor on her head.
