The Someone Like You singer, who is currently recovering from throat surgery, has always relied on her management to update her Twitter page.
But the 23-year-old wrote an update for her followers today after challenging 10,000 of her fans to start following a charity's Twitter account.
She tweeted: 'Right! It’s me! I will start tweeting if 10k of you start following @drop4drop and their trip to India this week. It’s a wonderful charity. Go!'
The London-born star later posted a picture on her Twitter page of herself posing alongside the poster for Beyoncé's new DVD, Live At Roseland.
She tweeted: 'F*** me, that was quick! Thank you! I'm in bed, watching Gladiator, eating an apple. Here’s a pic of me and Queen B last week in NYC!'
