The Hills stars Heidi Montag and Spencer Pratt and Frenchy Morgan will return to Celebrity Big Brother 2017
It's believed Heidi and Spencer were at the top of bosses' lists for the spin-off, which kicks off in January and will see old housemates take on new contestants, as they know they'll struggle to hold their tongues when put against other strong characters, because they proved such a hit with viewers when they took part in the series in 2013.
The insider told Daily Star newspaper: "Last time they were not sure what to expect, but they've become big fans of the show since their stint in the house. And they're sure they've devised the secret strategy that will see them win it. They will be even sneakier and more manipulative than last time, and won't hesitate to throw anyone under the bus."
The full line up for the spin-off is yet to be announced but James Jordan, who wasn't afraid to let loose with his acid tongue in 2014, and Angélique 'Frenchy' Morgan, who appeared on the show in 2012, have also been in talks with bosses about starring in the special.
The controversial 41-year-old model, who appeared on the reality TV show in 2014 but became the third contestant to get the boot, has reportedly signed a mega-money deal to take part.
A source told The Daily Star: "This time she is thinking bigger and better. She wants to make a serious impact on the house so she's planning all kinds of tricks to wind them up."http://www.mirror.co.uk/tv/tv-news/hills-stars-heidi-montag-spencer-9319632
