Celebrity Big Brother 2013: Spencer Pratt and Heidi Montag arrive in London

Heidi Montag and Spencer Pratt

Reality stars Heidi Montag and Spencer Pratt have arrived in the UK ahead of Celebrity Big Brother 2013.

The Hills stars are widely expected to be taking part in the new series, which starts this week on Channel 5.

The husband and wife duo are expected to compete together as one housemate, entering, nominating and ultimately leaving together.

The pair previously competed in the US version of I'm A Celebrity Get Me Out Of Here together, and coming from MTV series The Hills, it's clear they have no aversion to reality telly.

However their fellow LA star Lindsay Lohan won't be taking part in the show, despite also landing in the UK this week amid speculation she'd be entering the house too.

Sources ‘close to Lindsay’ told TMZ this week that the Mean Girls star has “no interesting in doing Celebrity Big Big Brother.”

The pals claimed that the reports were “completely untrue” and “nonsense”.

Celebrity Big Brother starts on Thursday night at 9PM on Channel 5.
