Pablo Montero's character Diego Lascurain is just starting to make his mark on "Mi Corazón Es Tuyo," but rumor is he may be replaced.

Although Diego has now started dating main character Ana, he may be written off the show because of Montero's behavior. According to TV y Novelas, the actor is having differences with the production schedule. He is supposedly not very punctual.

For a telenovela, which has a very long shooting schedule, time is very important, so the actor may be replaced with another. The problem with replacing him is that audiences would notice and miss his character, but producer Juan Osorio is supposedly eyeing William Levy to get people's minds off of Montero.

Although Levy is open to returning to Mexico, he is in the middle of promoting his new film, "Addicted."

Plus, the Cuban actor has explained that he is focused on Hollywood.

"Well, for now we are focused on movies, and we're thinking about that," he said. "In the future, if God wants it to be so, I would love to do something here in Mexico. I enjoy Mexico. I love Mexico."

Perhaps the only way to get Levy on board is to have him play a small, but important character, where he won't need to be on set as often as possible.

Producer Juan Osorio has been said to be very particular about what goes on in his telenovela. Supposedly, he placed some of the cast members on a diet.

Osorio didn't want the children to become overweight and promote obesity because it's such a problem. His own son, who portrays Sebastian Lascurain, was not exempt from the diet. Jorge Salinas, who plays dad Fernando Lascurain, was also on a diet, as he was supposed to look better as the show went on.
