New York, Sept 19: A Canadian celebrity chef has given a insight into the diva act that celebs like Justin Timberlake and Nelly Furtado put up when they visited the Rain restaurant in Toronto, Canada recently.

Chef Guy Rubino revealed that after reserving a table for 10, Furtado showed up late and brought in five extra people.

Rubino also claimed that the singer objected to the pre-fixe type menu and was rude to him.

He added that her manager ordered them to prepare individual dishes.

"She made a reservation for 10 guests. She showed up an hour late, with five extra people in tow," the New York Daily News quoted him, as saying.

 "For parties that size, we do a prix-fixe type of menu. Nelly objected and was really rude about it. She expected individual dishes to be prepared.

"Her manager even came into the kitchen and had the gall to say, 'Just f—ing do it!' I told her that she and her client could 'just f—ing LEAVE.'" He added.

Rubino also recounted Timberlake's outrageous restaurant manners.

"Timberlake [center] comes into Rain, doesn't even look at the menu and shouts for random food that we don't make," Rubino said

"If he knew what he wanted, why come to an Asian restaurant in the first place," he added.

However, the chef lavished praises on regular customers like Michael Douglas and Catherine Zeta-Jones have sophisticated tastes and are lovely.

 "They're very polite. Every time they come in, they pop into the kitchen to say hello. I just love them,” he said. (With Inputs from ANI)
