London - Usher is trying to convince Justin Bieber to go vegan.
The Climax singer thinks eliminating all animal products from his diet has been good for his body and is keen to convince his young protege to do the same.
A source told RadarOnline.com: “Usher frequents a few vegan restaurants in New York City and not only loves the food, but feels like it's the healthiest way to live.
“He's desperate to get Bieber on the same health kick he is and thinks with all the touring and busy schedule he has, it would keep him energised.”
The 33-year-old star - famed for his toned body - has been health conscious since his father died of a heart attack in 2008 and wants to impress the message of healthy eating on Justin.
The source added: “Usher is really close to Bieber so he's pushing the importance of eating healthy on him and it's something he takes really serious.
“So far Bieber's not feeling it, but he looks up to Usher as his mentor, so it won't be ruled out!”
Justin, 18, certainly hadn't given up on meat earlier this year, as he celebrated winning at the Billboard Music Awards in May by dining out at fancy steak restaurant N9NE at the Palms restaurant in Las Vegas.
Meanwhile, although he enjoys the food, it is not known if Usher has also started to embrace the ethical side of veganism just yet, as he has previously been urged by an animal rights charity to stop buying fur coats as presents for his friends. - Bang Showbiz
