Former The Hills stars Heidi Montag and Spencer Pratt have fuelled rumours that they will be appearing on Celebrity Big Brother after arriving in London.
There has been a copious amount of speculation surrounding contestants for the Channel 5 reality TV show, which will begin this week.
According to the Daily Star, Montag and Pratt could enter the house as one contestant.
A source said: "Just like when Jedward were in the house, Spencer and Heidi will be considered to be one housemate."
Last year, Pratt spoke to The Daily Beast, revealing that money was tight and that he and wife Montag - who met while filming American reality TV series The Hills - were living at his parents' home.
Pratt said: "Reality TV is not a career. Anyone who says, 'Oh, you can have a career in reality' - that is a lie."
Despite the lineup for the reality show not being confirmed, former X Factor contestant Rylan Clark was this week revealed to be the bookies' favourite to win the series.
Meanwhile, Lindsay Lohan and Katie Price have allegedly confirmed that they will not be starring in the show.
Celebrity Big Brother 2013 launches on Channel 5 on Thursday, January 3 at 9pm.
