Last night Katy Perry, who is supposed to marry Russell Brand this fall, let it slip that she may have already married him.

Appearing on Graham Norton’s chatshow, Katy said: “Life’s never dull with him – that’s why I married him!”

After hearing a surprised gasp from the audience, Katy quickly added: “That’s why I’m marrying him!”

Katy then refused to talk about her slip of the tongue, but later in the tv programme she also referred to Russel’s mother as her “mother-in-law”.

The possibility of a secret marriage get bigger since these aren’t the first slips. Russell often calls Katy Perry his wife and also refers to Katy’s parents as his parents-in-law. If they are just slips of the tongue, or little secrets that keep popping out – nobody knows.
