A source says, “Rob was a complete mess over Kristen’s cheating and began drinking to numb the heartbreak. Rob doesn’t just drink with friends while out, he drinks by himself at home and always reeks of alcohol. Rob even has plans to open an exclusive bar on Cahuenga Blvd in Hollywood, where he can party in peace and not have to worry if anyone’s watching.” Robert Pattinson and Kristen Stewart recently bought a Karaoke machine. A source tells the Sun, ''They both absolutely love karaoke. They used to go to bars whenever they could, but more often than not they'd get hassled by people. So Rob surprised Kristen with their own machine. It's top-of-the-range stuff with built in disco lights, a huge screen and even its own mini stage. Now they have karaoke parties at their home in the Los Feliz neighborhood of Los Angeles with all their friends. They go on until the early hours - even after a night out they head back to Rob and Kristen's got a good old late-night sing-along.''
