Rihanna got a special visit from one of today's most recognized soccer stars, Cristiano Ronaldo, at a concert stop in Lisbon on her Diamonds World Tour on May 28.

The international athlete, who plays for Real Madrid in Spain, took a snap with RiRi that is causing a lot of rumors of a romantic link between the two, according to 4 Music. Apparently, it looks as if the "Stay" singer is getting revenge or moving on from ex-boyfriend, Chris Brown, who is currently shacking up with his ex, model Karrueche Tran.

The handsome sports star tweeted a cute and cozy photo with Rihanna with the caption, "Yesterday at Rihanna concert," last week. Ronaldo gives the "peace" sign and flexed his bulging bicep while Rihanna gave a tough-girl look with her facial expression and crossed arms.

Then, the "Diamonds" singer lit a romance match by tweeting this juicy comment, along with an Instagram photo of them backstage, on May 29. In the picture, Rihanna puckered her lips together as if blowing a kiss.

Many are speculating that perhaps Cupid's arrow hit the singer and the in-shape baller, who just reached one million followers on Instagram and who could possible become the world's highest-paid player, according to 4 Music.
