Singer John Legend has expressed his sympathy for British singer Robbie Williams - claiming that he can’t understand why the ‘Feel’ star hasn’t had much success in America.

Robbie, who is one the UK’s best-selling male solo artists has had trouble have the same success in America.

In an interview with British newspaper The Sun, John, who has won five Grammy Awards said: “I’m stunned as to why Robbie’s not that done well in America.

“It’s a difficult market to crack. Americans’ music taste changes all of the time.

“I’m lucky things have worked out for me.

“I’m glad I’m known for making good music rather than for partying like some people. I also would hate to have a celebrity girlfriend. I do like to party though – I just do it private!

John, whose, biggest his is ‘Ordinary People’ continued:: “I heard about the deal that Robbie got and how they were expecting big things in the States but sometimes certain things don’t catch on and some countries are more culturally-specific.

“If I’m honest I don’t know why is didn’t work out however I know he’s a real hit in the UK. He’s a likable guy.”

The singer also revealed his admiration for British singers Amy Winehouse, Lily Allen, Joss Stone & James Blunt, He said: “Joss is really sweet and talented. I’ve worked with her a few times now and she deserves her success.

“Lily is fresh. She brings something completely different to the music scene and James Blunt is great. He certainly likes to party.”

He added: “But Amy is way above everyone else. I love her – I met her when we were doing the Jools Holland show. I think she’s really talented and has one of the most distinctive and cool voices in pop music right now and the Americans love her.

“I’d rate her as one of the top five female singers in music.

“Obviously she has her problems in her private life but she has one of the best voices I’ve ever heard.

“I’d love to work with her.”

John also said that he hopes to work with ‘Thriller’ star Michael Jackson on his highly anticipated new album, he told The Sun: “I wrote one idea for Michael Jackson but I don’t know if he’ll use it.

“The song was with Will I Am for him which I thought he might like. Let’s see.”

John added: “Acting is something I’d really like to try too at some point,” he said.

“I’ve got very little acting experience but I’m in talks with a few film companies about a few different movie ideas.

“A lot of people have approached me and think I’ll be good at it. I only want to do it if I can do a really good job. I don’t like doing things half-heartedly.

“Music will always take priority – acting isn’t natural but I know I’m very good at singing and writing songs.”
