Love Island star Yewande Biala will be joined by former contestants Chris Williamson and Marcel Somerville to speak to MPs about reality TV.
There is an investigation into the effects of appearing on shows like Love Island and The Jeremy Kyle Show.
Love Island has come under scrutiny over the aftercare it offers following the deaths of former contestants Sophie Gradon and Mike Thalassitis.
Williamson, Somerville and Biala will appear before the Digital, Culture, Media and Sport Committee later today.
The committee will discuss “representations of race, gender and body image and contestant preparedness for life after Love Island”.
MPs will also hear from a former guest on The Jeremy Kyle Show, which was axed by ITV in May following the death of participant Steve Dymond.
Show guests Dwayne Davison and Robert Gregory will offer evidence about their time on the show having claimed, according to MPs, that “the aftercare given to them was not robust and has had a serious negative impact on their lives”.
The committee has also been investigating the use of lie detector and DNA tests on the former show.
MPs have criticised TV bosses for not knowing enough about lie detector tests.
Mr Dymond, 63, died around a week after reportedly failing a love-cheat lie detector test on Kyle’s daytime show.
The construction worker was found in his room in Portsmouth on May 9 after splitting from on-off fiancée Jane Callaghan.
