It's one of the perks of working at Google that the company stages occasional talks by notable celebrities.
Past appearances have included the US president (when he was still a candidate), academics like Noam Chomsky and, on a lighter note, the creator of XKCD Randall Munroe. Yesterday the guest speaker was Lady Gaga.
Google sourced 54,000 questions for the pop diva from all over the world and she generally wowed the audience, and in particular her host Marissa Mayer who spent most of the session looking star-struck.
One person in the audience told Sleuth he came out of the session with a lot more respect for the artiste than he had going in. You can see the whole video of her performance here.
Lady Gaga is no stranger to the technology world. She has signed deals with Monster cables and Polaroid to promote and develop products, one of an increasing number of celebrities to court, and be courted by, Silicon Valley.
She is certainly outpaced by will.i.am, who has presented at three tech conferences in the past year and has got himself appointed creative director at Intel.
The granddaddy of them all, however, is Bill Clinton, who has been giving pretty much the same speech at technology conferences for the past year, with payments rumoured to be as high as $50,000 a time. Nice work if you can get it.
