She might already be one of X Factor's success stories with several hit singles under her belt, but Diana Vickers is showing no signs of relaxing.
The singer says she has turned into a real machine in the studio, churning out future hits.
In fact, she is already thinking about album number two, which will be much more grown up.
"It's like my first album's more adventurous, crazy, sexier older sister," she revealed.
New single Wicked Heart also shows off this new naughtier side, as Diana sings about wanting a man she can't have.
