Ricky Martin shocked fans as he joined Madonna on stage as part of her Celebration Tour – but it wasn’t his performance that got people talking.

The 52-year-old singer seemed to be having the time of his life as he joined Madonna for her concert in Miami on Sunday. Ricky took pride of place next to the Queen of Pop during a performance of Vogue and he seemed to get aroused by the topless dancers.

The dancers were filmed grinding on Ricky’s lap and fans are convinced he got an erection during the sexy performance. “Wait a minute Ricky Martin is that a …..” one fan wrote as they shared a clip of the incident on X, formerly known as Twitter.

Someone who was at the concert, added: “Gotta say, I kind of saw it myself.” A third person posted: “Omg what did I just watch, Ricky Martin living his best life and I am totally here for it, yes honey.”

However, others jumped in to defend Ricky and said it was likely just his pants bunching up. “From his Instagram from what I saw is, the dancing dance close to him and push his pants up, and that’s how it look like he got an reaction but it’s just the pants,” one fan wrote. Another agreed: “Erm this is what trouser crotches often do.”

Ricky is yet to comment on the incident, but he has taken to Instagram to share a video of himself onstage. Alongside side it, he wrote: “Thank you @madonna my love! Always fun to be invited to the party! You all, CAN’T MISS THIS SHOW.”

Ricky has been close friends with Madonna for years after the pair first met in 1999 after his performance at the Grammy Awards. During an appearance on Live With Kelly and Mark earlier this year, Ricky explained: “She gave me a standing ovation.”

He then revealed Madonna went backstage following his performance to meet him. The two singers then joined forces for Madonna’s second-ever music collaboration with the song Be Careful (Cuidado Con Mi Corazón).
