During the third night of Rosalía's Lux Tour at Madrid's Movistar Arena on April 3, Spanish singer Aitana joined the performer in a candid 'confessional' segment. Aitana shared details of a troubled romance with an unnamed ex, prompting laughter and advice from Rosalía. Fans quickly speculated the ex was Sebastián Yatra.
Aitana appeared nervous as she entered the confessional before Rosalía's song 'La Perla'. 'Is this going to be published somewhere?' she asked the crowd, drawing laughs. Rosalía encouraged her to open up, and Aitana obliged, saying she had dated athletes, actors, and singers before recounting one specific story. As their one-year anniversary approached, her ex declared, 'After a year, I can be unfaithful.' Aitana noted, 'Well, at least he’s honest.' Rosalía quipped, 'He knew from the start that he had an expiration date.'
