Pink has urged fans not to read too much into her chart-topping new single 'So What' - because every line is a joke.
The singer's new hit - her first ever number one single - mocks her split from husband Carey Hart, and then pokes fun at Jessica Simpson.
But Pink insists she made up the lines to make her laugh - and targetted Simpson because of the way her name rhymed.
She explains to PopEater.com: "That song was a joke when I wrote it. I was like, 'Oh, this will be funny: I guess I just lost my husband, I don't know where he went.' And then it just kept going on from there, and every line was funnier than the last.
"Everyone thinks I'm trashing Jessica Simpson, but I'm actually not at all. I'm actually saying that she's cooler than me 'cause the waiter keeps taking my table and giving it to her."
She explains her alternative line was: "'The pilot just took my private jet and gave it to Haylie Duff.' But that wasn't as cool, so it ended up being Jessica Simpson."
'So What' currently tops singles charts in the US and UK.
