Lady Gaga: Queen of Twitter.

Rejoicing and giving thanks to her faithful Twitter followers, Lady GaGa showed her love for all of those responsible for making her the top user on the popular social networking site.

After setting records in the world of Facebook, the "Paparazzi" singer recently overtook former top tweeter Britney Spears with an oh-so-impressive 5.7 million followers.

Posting a video of gratitude, Gaga told, "This is Lady Gaga, queen of Twitter. I wanted to thank all of my beautiful little monsters for following me. Thank you for beginning my reign as Twitter queen. May you always have soft cuticles while tweeting. May you never have carpal tunnel. ... I vow to always tweet and tweet again."

Looking ever the beauty queen, Gaga toted a wand in her hand as she added, "Just remember that I love you and love yourself. I love you Twitter."

Whitney apologizes for voice in London, Blames Air-conditioner

Fans at London's O2 were left disappointed at Whitney Houston's concert on Sunday night, as the star was forced to apologise for her singing.

The 46-year-old, who is on her first tour of Britain in a decade, struggled through some of her best known hits.
"She doesn't want to come, my soprano friend," said the star, explaining her voice.

"Sometimes the old girl sings, but not tonight," Whitney told the crowd. "I want to do it, but she doesn't want to ... She's getting a little temperamental," she added.

The diva also had another excuse for her performance. "Turn the air-con off," she asked organisers, from the stage. "I can feel it. It takes away my soprano."

It is claimed some fans were so unimpressed by the star's comeback gig, they walked out.

But those who attended the star's Monday night show, also at the O2, had a different tale to tell. Many concert-goers said they thoroughly enjoyed it.

The first three dates of Whitney's UK tour in Manchester and Glasgow had to be postponed as she was suffering from a respiratory disorder.
