Socialite Kim Kardashian is laughing off reports she has secretly wed football player Reggie Bush, revealing she referred to him as her "hubby" online as a joke.

Rumours about their marriage started spreading after Kardashian hinted in a recent post on her own website that she and New Orleans Saints star Bush had exchanged vows.

She says, "I said hubby as a joke. ... He said, 'Don't use boyfriend, it's so typical.' He said, 'Write hubby or baby.' Everyone thought I was married."

But Kardashian insists she and Bush will wed some day: "We definitely make it work. ... This is the first relationship I've been in with no trust issues."
