How very N*E*R*D, we did think.
But just how do we know details of what was surely a very private moment?
Oh, well she did it in a London night club, y'see!
As you do and all that.

The pair were out at London's Rose club when Tulisa apparently got all frisky (cringe) to Missy Elliot's One Minute Man.
According to the Daily Mirror newspaper, the couple were snogging away all night and taking pictures of one another.
At one point, the paper reckons the pair stood up on top of a sofa for a hug in front of the whole club.
Tulisa, 24, was drinking £500-a-bottle (yes, you could go on holiday) pink champagne while Danny had a few vodka and lemonades.
On Wednesday Tulisa called Danny her "gorgeous hubby" as she sent him birthday greetings on Twitter.
She wrote: "Happy birthday to my gorgeous hubby @dannysimpson getting on now babes haha. Love u lots like jelly tots. hehe XxX"
Danny replied: "Let's have it, babe. Looking forward to opening my prezzies. Love ya x."
Hubby? LOVE YA? Er, jumping the gun much? It's only been two months.
