The London part of the telethon was held at The Hospital Club in Covent Garden. Pattinson was joined by Rihanna, Beyonce, Jay Z, Chris Martin, Bono and The Edge, who all performed.
The Twilight hunk was sporting a sexy scruffy new beard, earlier on in the evening he had implored viewers to "help Haiti get back on it's feet" during the moving money raising event.
Adding to the star power in London, Beyonce looked very glam and stylish in black leggings and a black and silver leather jacket.
Rihanna looked very fashionable as she turned up for the charity gig in a gray top and a large scarf.
Bono and The Edge went out for dinner near by at the Covent Garden hotel after practicing before the main event later in the evening and were more than happy meeting all their fans in London.
Chris Martin was also spotted leaving the event alone with his hood up and scarf on after Gwyneth Paltrow turned up to also get involved in the telethon.
