Lady Gaga says she was "saved" by Elton John.
The 'Pokerface' singer - who battled a drug addiction for two years - has revealed how the 'Candle In The Wind' star helped her through the hard times.
She said: "It's pretty messed up being friends with people who used to have drug and alcohol problems, like Elton.
"He got me on the straight and narrow. He was telling me: 'Gaga, you're smoking too much'. He saved me."
Lady Gaga - who is the godmother of Elton and his partner, David Furnish's son Elijah - has revealed that she realised she needed help for her addiction at her best friend, Bo O'Connor's wedding last year.
She said: "I've been friends with Bo for 20 years but when she got married I was her maid of honour.
"I was going through a really hard time and I was high and I was f***ed up throughout her whole wedding.
"For the rehearsals, for the planning, for the day - and I look back on that day and I remember it, but I'm really sorry I was f***ed up at her wedding because she deserved a sober maid of honour."
Meanwhile, the 28-year-old singer has revealed that she is still on the road to recovery.
Speaking at her artRAVE tour in Sheffield, England as reported in the Sun newspaper, she said: "I'm sober now. Sometimes. Not always. Just when I'm on stage."
