Ciara gets physical in her sexiest video yet for “Ride,” the first single from her fourth album Basic Instinct, coming this summer. Director Diane Martel (“Love Sex Magic”) takes a minimalistic approach, choosing to highlight the R&B siren’s performance and her bountiful assets. CiCi works her body like a gymnast, straddles a mechanical bull, and teases her fellow ATLien Ludacris with her goodies. This is one “Ride” you won’t want to end.
