Shakira wore a chic black dress, which featured a sheer overlay on top of a tulle skirt. She completed the ensemble with strappy black stilettos, a gold clutch and her hair styled in a half-up, half-down 'do. Piqué complemented her look, sporting a classic black tuxedo, bow tie and gigantic grin.
"Gracias a Antonella y Leo y a la gente de Rosario por su hospitalidad," Shakira captioned a photo of the two posing together, which translates to, "Thank you to Antonella and Leo and the people of Rosario for your hospitality."
While Shakira surely turned heads in the sexy number, all eyes were on Roccuzzo. The blushing bride wore a stunning strapless gown with a long train, with her gorgeous brunette tresses styled in lush, bouncy waves. Messi looked dapper in a navy suit, sporting some scruff and a stylish white tie.
The newlyweds couldn't help themselves from sharing a few smooches as photographers snapped their pics outside of the venue.
At the reception, Roccuzzo and Messi appeared as happy as ever. At one point, they were serenaded by Abel Pintos, a famous Argentinean singer, and yes, there was another sweet kiss...
Ahead of the wedding, Piqué, 30, and Shakira, 40, were adorably spotted holding hands as they arrived to Argentina on Friday. The two were both donning black head-to-toe, seemingly keeping a low profile by shading their faces with a baseball hat and sunglasses.
