Jennifer Lopez wasn’t happy when her chef served her rice while she was training for the Super Bowl

Jennifer Lopez‘s personal chef Kelvin Fernandez’s job is keeping up with the superstar’s ‘intense’ diet.

But the culinary pro told Us Weekly how he learned what happens when you accidentally make the triple threat stray from her diet the hard way.

Kelvin said he got a talking to after putting rice on the table while J.Lo was in the thick of training for her Super Bowl performance.

‘If I mess up once I will hear it and she deserves to put me on my point,’ he admitted.

‘One time I tried to be nice and I’m like, “Alright the woman’s worked hard. She deserves it. Let me do dinner family-style.”

‘The next day she’s like, “Kelvin, you served me rice.” And I’m like, “No, no, no, no, no, there was chicken, there was salad. You grabbed the rice!”

Though she was able to ‘joke’ about the indulgence, it helped Fernandez come up with a plan.

‘From that moment I said, “Alright, Jennifer. I’m going to serve you every single plate individually. Do not look at anyone else’s plate. Do not look at what anyone else has.”‘

Kelvin said he admires the Hustlers actress’ dedication and willpower.

Hard work pays off: 'She’s such a hard worker. When she puts her mind to something, it’s incredible how much can be accomplished. When she wants something healthy, she’ll stick to it' he said

Her Super Bowl plan included cutting carbs and sugar out of her diet intermittently, something that was a new challenge for the chef.

‘It was one of those things where she was eating almost the same thing every single day. There were simple carbs and complex carbs and different types of carbs that we had to implicate into the breakfast, lunch and dinner structure,’ Fernandez said.

‘I’ve never had breakfast vegetables before, but this woman was having egg white scramble with vegetables three different ways and every single day.’ 

He went on: ‘She’s such a hard worker. When she puts her mind to something, it’s incredible how much can be accomplished. When she wants something healthy, she’ll stick to it.’

‘They rarely ever are in the mood for anything [special], but the cool thing about it is when they are, that’s when I get challenged,’ he said, revealing he once prepared a spread of homemade sushi for Jennifer and Alex.

But with the kids, Kelvin gets to be a bit more adventurous. Lopez is mom 12-year-old twins Max and Emme and Rodriguez raises daughters Natasha, 15, and Ella, 12.

‘I have the free reign of what to cook, so in the morning for breakfast I get crazy with the kids,’ he said.

‘I’ll do Captain Crunch-crusted french toast and eggs Benedict. Alex’s girls love my bacon, egg and cheese waffle sandwich.’
