Shakira has grabbed the second position on the list. She has just released an album She Wolf.
The supposed presence of Shakira on the island has stirred new interest in the insistent pregnancy rumours surrounding the Colombian artist, who has been in a relationship with the FC Barcelona defender for years.
The Colombian magazine Gente said that the singer and the athlete will be parents of a baby boy to be born in late January 2013 and that they have already given it the nickname Ulicito.
The publication said it has seen the results of the latest ultrasound that the Colombian had in Miami 10 days ago.
The artist's agents in Colombia told EFE that the couple is sticking to their decision not to say a word about any possible pregnancy.
The last time the singer appeared in Puerto Rico was in October 2011 on her Sale el Sol (Sunrise) tour.
Pique will stay in Puerto Rico until Wednesday night, when he will head back to Spain after the friendly match.
