The rumor mill has been working overtime ever since music icon Prince passed away on April 21 at the age of 57.

The cause of death has yet to be released, but TMZ and other tabloids have reported that the artist was taking prescription drugs and treated for an overdose just days before his passing.

Though police are now investigating the possibility of an OD, too, Prince’s former personal chef, Ray Roberts, cast aspersions on the claims, telling the Associated Press on Sunday that he hadn’t seen “even a hint” of the singer abusing drugs. “Not at all,” he said. 

Roberts, who began cooking for Prince at his Paisley Park estate in Minneapolis in 2013, said the artist had been suffering from stomach and throat problems for months.

“It felt like he wasn't himself probably the last month or two," he told the AP, noting that he had become to prepare more juices and smoothies. "I think he was just struggling with being sick a lot."

Voted the world’s "Sexiest Vegetarian" by PETA in 2006, Prince ensured that meat was all but forbidden at Paisley Park. According to Roberts, the star ate mostly soups and salads, and preferred ingredients like roasted beets and pesto broccolini.

"I don't know if it was just an unwritten rule, but there was no meat there — ever," said Roberts, who also runs a small chain of restaurants with his wife and occasionally accompanied Prince on his tours. "If somebody wanted to eat meat, they would have to eat it in the parking lot. And he was very serious about this."

“I wish he was still here," he added in the interview, fighting back tears.

Prince's curious food proclivities are well-documented. According to a 1984 Rolling Stone story, Prince loved to pair orange juice with spaghetti and tomato sauce. TODAY Food notes that some of the artist’s songs also hinted at his unique palette and distaste for dairy.

“Oh great, now you think you're my soulmate. You don't even know what kind of cereal I like,” Prince raps on the song “Joint 2 Joint” from 1996's Emancipation. “Wrong! Cap'n Crunch with soy milk. Because cows are for calves.”
