After revealing too much about his relationship with Jennifer Aniston, American singer John Mayer is kissing and telling again.
The 32-year-old proves he isn't much of a gentleman - yet again - as he describes his 'crazy' sex life with ex-girlfriend Jessica Simpson in a new interview.
Speaking in the March issue of Playboy magazine, he describes Simpson, 29, as 'sexual napalm' in the bedroom.

Mayer and Simpson dated on and off for 10 months from August 2006 - nine months after her high-profile split from husband and Newlyweds co-star Nick Lachey.
The singer admitted their relationship was sexually charged, describing Simpson as 'a drug'.
He explained: 'And drugs aren't good for you if you do lots of them... Yeah, that girl is like crack cocaine to me.
'Sexually it was crazy. That's all I'll say. It was like napalm, sexual napalm. Did you ever say, "I want to quit my life and just f**king snort you?"'
Mayer's claims about Simpson's bedroom skills will no doubt come as a surprise to her fans after she famously claimed to remain a virgin before she married Lachey in 2002.
Shock: Jessica Simpson said she was having an 'interesting' day on her Twitter page on Wednesday after Mayer's revelations
After excerpts of the interview with Mayer were published this week, a stunned Simpson wrote on her Twitter page today: '
Interesting day so far... hmm... at least I am boxing two-a-days this week.'
Mayer also addresses his high-profile on/off relationship with Aniston, who he split from last March after a total of nine months together.
Suggesting it was his decision to end their relationship for the second time, he said: 'We just have a regard for each other’s feelings that is pretty intense. It’s been a deep relationship, and it’s no longer taking place at all.
'Have you ever loved somebody, loved her completely, but had to end the relationship for life reasons?'
Suggesting the nine-year age gap between the couple may have been a problem, he elaborated: 'In some ways I wish I could be with her. But I can’t change the fact that I need to be 32...
'But 32 just comes roaring out of me at points when I don’t see it coming. I want to dance. I want to get on an airplane and be like a ninja. I want to be an explorer. I want to be like The Bourne Identity. I don’t want to pet dogs in the kitchen.'
He also admitted he had slept with about 'four or five' women since he split with Aniston last year.

He added: 'But even if I said 12, that's a reasonable number. So is 15. Here's the thing: I get less a** now than I did when I was in a local band. Because now I don't like jumping through hoops.'
When Mayer and Aniston first split up in August 2008 after four months together, the singer held an impromptu press conference outside a New York City gym, revealing that he was the one who ended their relationship.
He said: 'Have me as a man who ended a relationship stand here and write some truth.
'Have me stand up for somebody and write that Jennifer Aniston is the smartest, most sophisticated person I think I've ever met.
Brief fling: Mayer dated Jennifer Love Hewitt in 2002
'She's one of the most lovely people I've ever met in my life and I'm going through something that's a very personal thing and you have to give that up...
'There's no lying, there's no cheating. There's no nothing. People are different, they have different chemistry, they have different lives.
'I ended a relationship because there is no lying. I ended a relationship to be alone because I don't want to waste somebody's time if something's not right. I don't waste people's time.'
Despite his public outburst, Aniston forgave him and they reconciled two months later, with her telling Vogue magazine, he wouldn't be talking so publicly about her again.
She said: 'Trust me, you’ll never see that happen again from that man.'
Aniston and Simpson aren't the only famous females which Mayer has spilled the beans over - he also discussed his brief coupling with actress Jennifer Love Hewitt.
Mayer and Hewitt dated in 2002 and the curvy star was said to have inspired one of his biggest hits Your Body Is A Wonderland.
The singer discussed their relationship during a stand-up gig in Hollywood four years ago, claiming he never got to have sex with her because she had a bout of food poisoning brought on by some bad fish on their date.
He later apologised, saying: '
It really was me making fun of myself.'
