A-listers have been leaving the social networking site in their droves in aid of World AIDS Day - find out how you can help and what the stars are up to, here.
Some of Twitter’s most popular celebrities – including A-listers Lady Gaga, Justin Timberlake, Jennifer Hudson and Usher – have pledged to quit the social networking site in a high profile campaign to raise money for World AIDS Day.

The Digital Life Sacrifice initiative has been organised by songstress Alicia Keys in aid of Keep a Child Alive – a charity linked to World AIDS Day – and has had stars all over Hollywood signing off from Facebook and Twitter.
The iconic A-listers have all refused to update their glittering posts again until one million dollars (around £640,000) is raised by their followers for Aids charities, and - to prove they're taking things seriously - will even be pictured in coffins to advertise their digital deaths.
But don’t despair – they won’t be gone for good. You can buy them back by visiting buyalife.org, and donating some much-needed cash towards your favourite celeb. The sooner the money is raised, the sooner they’ll be back to their usual Tweeting habits, so start giving!
And it’s not just famous faces who can get involved in the campaign, either. The charitable Ms Keys is encouraging everyone to have a go, and sign off from Twitter, from tomorrow.
‘It just doesn't have to be just because you're a celebrity or something like that. It can be anybody,’ the new mum revealed.
The stars’ digital silence begins on World AIDS Day, tomorrow.
