Habbo, one of the glut of online communities targeting 11 to 18-year-olds, is teaming up with pop stars such as Lily Allen and X-Factor winner Shayne Ward to encourage more teens to use its chat and gaming facilities.
The tie-ups have been organised by Spring PR, which is running a UK consumer campaign for the site after a non-competitive pitch.
Habbo claims more than 5.4 million users worldwide and is owned by Finnish-based interactive entertainment company Sulake.
Spring director Danielle Windsor added: ‘Jamelia is launching a salon and we aim to stage the world's biggest online pub-quiz with U2.'
