The death of 48-year-old Whitney Houston has shocked the world and modern music's biggest personalities have taken to social networking site Twitter to pay their respects. 

It was confirmed late last night (February 11) that the 'I Wanna Dance With Somebody' sensation had been found dead and tributes have been pouring in from celebrities and pop stars around the globe. 

Bajan beauty Rihanna, who is currently rehearsing for tonight's GRAMMY Awards, tweeted: "No words! Just tears #Dear Whitney. I honestly can't think of anything else!!!"

"So devastating," Katy Perry also wrote. "We will always love you Whitney, R.I.P."

'Grenade' hitmaker Bruno Mars added that he was "sick to my stomach, nobody sang like Whitney" and teen superstar Justin Bieber posted a message of sadness after hearing the news:

"Just heard the news. So crazy. One of the GREATEST VOICES EVER just passed. RIP Whitney Houston. My prayers go out to her friends and family."

Enrique Iglesias, who recorded a duet with Houston back in '00 with 'Could I Have This Kiss Forever', also took to the website to tell his fans that he's heartbroken over her tragic passing:

"My thoughts and prayers go out to Whitney and her entire family. Working with her is an experience that I will cherish forever."
