The fashion-forward star couldn't have looked cooler.
The "Love on the Brain" singer put her long legs on display in a pair of denim hotpants, which she paired with a flaming blouse by Vetements. RiRi left the top unbuttoned, showing off a Missoni bikini top underneath. She finished the look with a colorful Fendi purse, black heels and sunglasses.
Rocky, meanwhile, sported a more casual ensemble. The artist paired sweats and a T-shirt with a dark hoodie.
“Between takes they were very lovey dovey” a source told ET, adding that the couple was hugging and not shying away from PDA.
"They are so madly in love,” ET's source added of Rihanna and Rocky. "They barely leave each other’s side... A$AP is so grateful for Rihanna. She's his biggest cheerleader and he doesn’t take her for granted."
