Meanwhile, a blog is claiming that Rob left Ivy Club on March 18, "slightly under the influence of alcohol" and even posted a very intriguing photo. However, other news sources and blogs reported that Rob might be 'sleepy' after working the whole day. Even Daily Mail's report never mentioned any 'drunk' incident. The UK entertainment site reports: "By the time he was escorted out the back entrance and back to his hotel Pattinson had a wide, if slightly lop-sided, smile on his face."  Photo by: Fame Pictures
