Leona is really getting into the habit of making us pay attention to her.

The X Factor star was seen acting very out of character at Barney’s Beanery in Los Angeles, a bar famed for its drunken, rock-star clientele.

One of the bar’s most famous regulars was Janis Joplin who died from a heroin overdose in 1970, aged just 27. For 25-year-old Leona, who was telling everyone how Janis was her inspiration, this is probably the most exciting thing she has ever done in her life.
