The 22-year-old from Guadalajara, resplendent in a flowing ruby-red evening gown, has been modeling since she was 15, but nothing could quite prepare her for her moment of glory.

"I did feel surprised, I just went blank," the brunette beauty said of her crowning achievement. "There was nothing going through my mind. I was in a state of shock."

All hail the Queen of Twitter

An "inaugural message" posted by the pop music diva at her official YouTube channel had been viewed 345,145 times by Monday afternoon.

"Thank you for beginning my reign as Twitter Queen," Lady Gaga said in video that showed her sitting at a make-up table backstage with a lacy crown atop her head and a glowing wand in one hand.

"I vow never to partake in online shenanigans and I vow to always tweet and tweet again."

Lady Gaga, whose birth name is Stefani Germanotta, posted the video after getting word that she had replaced Britney as the person with the greatest following at microblogging service Twitter.

The music star known for creative outfits had 5,750,270 followers at Twitter as of early Monday in California, while there were 5,712,098 people signed on to receive musings or other terse missives fired off at the service by Britney.

Others in the club of Twitter users with more than five million followers included US president Barack Obama and celebrities Ashton Kutcher and Ellen DeGeneres.

As with fame, popularity at Twitter is subject to the whims of fans.

"May you always have cropped cuticles while tweeting and may you never have carpal tunnel," Lady Gaga said, referring to a repetitive stress injury sometimes caused by too much typing. AFP Relaxnews
