Floyd Mayweather Jr is reportedly paying his chef $1,000 (£680) per meal until the Manny Pacquaio fight on May 2.
The California-born chef, known as Chef Q, will cook for the boxer on a 24/7 basis, and has identified herself on Instagram as 'The Chef that's Beastin in Floyd Mayweather's Kitchen'.
With 46 days left until fight night, Chef Q could earn $184,000 (£125,375) if she cooks Mayweather four meals a day.
Talking to TMZ, she said: "I am here for him any time. 24 hours, seven days a week. If he needs me at 3am, I am there cooking up breakfast.
"He's always been mindful of what he eats but there is something different about this fight."
Mayweather, regarded as the number one pound-for-pound fighter in the world, boasts an undefeated record in 47 bouts.
