The former 'The Hills' star and her husband Spencer Pratt could conceive their first child in the 'Celebrity Big Brother' house as she is "hopeful" they will have a baby in 2017.

Speaking to Faithwire last year, she shared: "I am writing a coffee table wife type of book. It's more like a fun project, something I enjoy doing, and then I'm getting ready to be a mom hopefully next year ...

"You know, I had to pray to get my husband to even agree to have a kid, and so this whole journey over the last few years ... I have had to do."

The couple - who were the first celebrities to enter the 'Celebrity Big Brother' house on Tuesday (03.01.17) -have impressed on the reality programme so far and were initially part of team of All Stars selected to decide which celebrity they wanted to "edit out" of the show and banish to the garden.

Along with other contestants - including Coleen Nolan and Calum Best - Heidi and Spencer opted to edit out 'X Factor USA' star Stacy Francis and then later actor James Cosmo.

It comes after it was claimed that Heidi and Spencer would consider not taking part in the show if their demands were not met.

Speaking before the launch, which took place on Tuesday (03.01.17), a source shared: "We're hours away from launch and now Speidi have thrown a spanner in the works. They're clearly up to their old tricks again."

The couple - who have been married since 2009 - reportedly requested they were given fish and chips whenever they wanted and said they would not be entering the house if their wishes weren't granted.
