Paparazzi snapped the pair locking lips last week as they cuddled on a chaise and played in the surf while vacationing in Cancun, Mexico. The dewy model made sure to avoid tan lines by ditching her bikini top for their ocean-set frolicking session (see video -- with Delevingne's important bits black-barred out -- here).
Michelle, 35, and Cara, 21, were also photographed kissing in Miami on Sunday as they climbed into an SUV on the way to a music festival.
Word is, the two were introduced late last year by mutual friend Rihanna and quickly hit it off.
"She's so cool," Rodriguez supposedly said of Delevingne back in February. "When we started hanging out, I just thought she was awesome, and we have the best time together. She's hard though. You wouldn't want to mess with her in a fight."
