Kenia Os reveals during Rosalía’s LUX Tour her ex cheated: Who could it be?

Kenia Os turned her surprise appearance at Rosalía’s LUX Tour in Mexico City into a major celebrity relationship reveal. The Mexican singer joined Rosalía onstage at the Palacio de los Deportes, where she opened up about an ex-boyfriend who allegedly betrayed her trust after insisting there was nothing going on with another woman. The confession quickly raised one question: Who was Kenia Os talking about?

While fans may immediately think of her high-profile relationship with Peso Pluma, details Kenia shared about the timeline have also led to speculation about Gera MX. However, the singer never identified the ex by name.

Kenia Os reveals cheating story during Rosalía’s LUX Tour in Mexico City

Rosalía welcomed Kenia Os during the first night of her LUX Tour in Mexico City, but their joint appearance took an unexpected turn when Kenia entered the show’s onstage “confessional.”

Kenia began by explaining that the relationship drama happened around the time she was preparing for an important career milestone. “I want to start this story by telling you that I was on tour. I was going to leave the country for several weeks. It was a very important tour, my first tour in the United States,” Kenia told Rosalía.

Because Kenia and the man she was dating were both singers, she said they discussed how they would handle spending time apart. “So, like the good people and singers getting to know each other that we were, we promised each other peace, calm, harmony, no shady stuff. You know, the typical situation when you’re dating long-distance and you’re both singers,” she added.

How did Kenia Os discover her ex was seeing another woman?

Kenia said the first warning sign came from social media. According to the “Malas Decisiones” singer, her then-boyfriend had secretly tagged another woman. Kenia’s friends helped her notice the suspicious activity. “How did I find out? I have a lot of girlfriends and a lot of gay friends,” she told the crowd at Palacio de los Deportes.

Rosalía jumped into the story with her own observation. “Girlfriends and gays are always the best detectives in the entire world,” she joked.

Instead of ignoring what she had discovered, Kenia confronted the man directly. “Obviously, I asked him why he had secretly tagged her,” she explained.

Kenia said she also made it clear that she did not want to jump to conclusions. “I told him, ‘You never tell me anything about her, and I don’t want to look crazy. I want us to take some time apart because we’re still getting to know each other.’”

They agreed to take a break, but what happened afterward seemingly validated Kenia’s suspicions.

Kenia Os says her ex denied having feelings for the other woman

According to Kenia, her ex insisted there was no romantic connection with the woman she had questioned him about. “Like a good man, he told me, ‘There’s nothing going on. You’re crazy. Not at all. I would never date her!’” she recalled.

But Kenia claimed the situation changed almost immediately after they decided to spend time apart. “During the time we were taking apart, which was a very short time, like 10 days, he started going out with her,” she said. “I think they started a relationship three weeks later.”

The revelation prompted a huge reaction from Rosalía’s Mexico City audience. “But anyway, I’m not here to talk about that. I’m here to ask, what can we take away from all of this, Rosi?” she said.

Her conclusion was simple. “A woman’s intuition is never wrong. And when they tell you it’s not her, it’s her!”

Kenia said the incident happened when she was preparing to leave for her first U.S. tour, which took place in September 2022. That timeline has caused fans to look back at her relationship history from that period.

Was Kenia Os talking about Gera MX?

Gera MX has emerged as one possible subject of fan speculation because of the timeline Kenia described.

Kenia Os and Gera MX had been romantically linked before publicly confirming their relationship in November 2022. Their romance ultimately ended, with Kenia previously discussing how their busy careers and schedules complicated the relationship.

The timing could explain why some fans believe Gera MX was the unnamed ex in her Rosalía LUX Tour confession. Kenia did not say Gera MX’s name during the story, nor did she explicitly connect the alleged cheating incident to their relationship.

Kenia Os and Gera MX eventually reunited professionally despite the end of their romance. The singers released “Rumores,” their second collaboration after “Diamantes.” The reunion sparked speculation that the pair could potentially revive their romantic relationship, but a reconciliation never happened.

Kenia later moved forward with other chapters of her personal and professional life, including her relationship with Peso Pluma and the evolution of her music career.
