Mi corazón es tuyo

Fernando Lascurain is a wealthy businessman and recent widower, attempting to raise his seven unruly children: Estefania "Fanny", Fernando "Nando", Alicia, Sebastian, Alex, Guille and Luz. He seeks the assistance of a new nanny, despite his children having driven away all the previous ones. He hires and falls in love with Ana Leal, a struggling exotic dancer who tries to hide her double life. Although Ana lacks experience and a refined education, she quickly bonds with the Lascurain children. Ana dreams of being a mother and also to find her lost-long mother, who left her in an orphanage at the age of three with only her beloved guitar, but when her home is destroyed following an accident, she must borrow money from her ruthless boss at "Chicago", the night club where she is secretly employed. When Fernando simultaneously falls for Ana and Isabela, an economist and sophisticated woman who is trained by her mother to marry a millionaire, he must choose between both women.^[8][9]

Just when Fernando realizes he's in love with Ana, he decides to marry Isabela instead, who is pregnant and he believes that the baby is his, when the father is actually Enrique, a fellow employee from their company and Isabela's ex-lover who secretly hates Fernando.

Fernando and Isabela marry, much to his children's dismay and Ana's heartbreak, and she later finds solace with Diego, Fernando's brother. Time pass and Isabela and Fernando's marriage fails because he still has feelings for Ana, and also because Isabela mistreats Fernando's children and Ana, and he sees her true colors and divorces her.

Soon, after many efforts, he manages to reconcile with Ana and proposes to her and she accepts, but Isabela sets him up to discover Ana's double life in the Chicago club and feeling deceived, he angrily calls off their engagement.

However, after almost losing Ana to a vengeful and insane Enrique (who dies before he could reveal to Fernando that he was the real father of Isabela's son, Diego Nicolas), Fernado forgives her and despite Isabela's efforts to sabotage them, they get married and Ana gives birth to twin girls and live happily with their ten children, while Isabela ends up morbidly obese, poor and alone.

The telenovela is an adaptation of the original Spanish television series, Ana y los 7. Based on the original script by Ana Obregón, who wrote and starred in the original series, the remake was adapted by writers Alejandro Pohlenz, Marcia del Río, and Pablo Ferrer. Juan Osorio serves as executive producer. The production of the telenovela officially started on April 21, 2014, at a shopping mall in Metepec, Mexico, outside of Mexico City. Although the majority of filming is conducted on soundstages at Televisa San Ángel in Mexico City, additional scenes are also filmed throughout the state of Mexico, where its governor, Eruviel Ávila Villegas, met with the cast during one day of filming.^[7][10] Some of the cast filmed scenes in Puerto Vallarta and a resort in Riviera Nayarit in late January 2015.^[11]
