Robbie Williams "prays to Elvis Presley" before he goes on stage.

The 'Party Like A Russian' hitmaker quipped that he has a few words to say to the King of Rock and Roll - who passed away in August 1977 - before every gig whilst sipping on a strong coffee.

Asked what he does before each show in a Q&A with fans on Twitter, he shared: "Espresso and pray to Elvis."

And the 42-year-old singer - who has four-year-old daughter Theodora and two-year-old son Charlton with his wife Ayda Field - also revealed how he likes to relax after a gig.

Taking to the microblogging site, he shared: "FIFA on x box, uno, Nandos (sic)"

Robbie is set to tour the UK and Europe next year and is particularly looking forward to singing 'Mixed Signals' to his thousands of fans but admits "it is really hard to sing".

Whilst the 'Heavy Entertainment Show' singer only answered a selection of questions that flooded in on the social media site, it is likely he read them all as he previously admitted he reads every message sent to him on social media even though it is "dangerous".

He said: "I read everything. Yes it's dangerous. Yes it crushes the soul. But I'm addicted to it. Yes I concentrate on the bad ones. I'm addicted to a lot of stuff that makes me feel full stop. Feel angry. There's an energy in that that's addictive. I'm addicted to stuff that strokes my ego, there's an energy to that. I'm addicted to everything about it."

And his decision to have Botox was also fuelled by comments made about him online.

He shared: "I've had Botox and some fillers and something done to my chin. And I really like it. With the last few albums I put out I looked on social media people were saying, 'F**k he's aged.' And I was like, 'Yeah, I have.' I was tired, I had mental illness and stress and whatever was going on up there was coming out in my face. The truth of my mind was written on my face."
