Who is Mariana Seoane?
Mariana Seoane is a Mexican actress, singer, and model who has worked in Spanish-language television for more than three decades.
She made her debut on Televisa in 1995 and spent the next two decades moving through leading and recurring roles in some of the most-watched telenovelas and crime series in Latin America.
Her acting career developed across two distinct phases: a first decade of romantic and supporting roles on Televisa productions, and a second decade of villain turns and crime drama work on Telemundo and Univisión.
That willingness to play antagonists gave her some of her most attention-grabbing performances.
Alongside her acting work, she released six pop albums between 2004 and 2012, two of which charted on the Billboard Latin Albums chart.

She is also known for her candid personality in interviews, including a 2023 conversation in which she confirmed she and singer Luis Miguel had a brief romantic connection during an earlier period of her career.
