Former reality TV stars will appear before MPs as part of an investigation into the format.
Dwayne Davison and Robert Gregory, who appeared on the Jeremy Kyle Show, will address MPs on the Digital, Culture, Media and Sport Committee.
MPs said both men “have said publicly that the aftercare given to them was not robust and has had a serious negative impact on their lives”.
The parliamentary investigation began following the death of show participant Steve Dymond, and ITV has since cancelled the programme.
Mr Dymond was found dead around a week after reportedly failing a ‘love-cheat’ lie detector test on Kyle’s daytime show.
The committee has been investigating the use of lie detector and DNA tests on the axed programme.
Kyle has been asked to appear before MPs but is yet to do so. He is currently piloting a new show for ITV.
Former Love Island celebrities Chris Williamson, Marcel Somerville and Yewande Biala will also talk to MPs about reality TV.
They are expected to discuss the role of producers in “influencing the behaviour of participants, the mental health support provided to participants and whether recent reforms have gone far enough”.
They will also talk about “representations of race, gender and body image and contestant preparedness for life after Love Island”.
Love Island has been under increased scrutiny over the support it offers contestants once they leave the show after the deaths of Sophie Gradon and Mike Thalassitis.
The committee will meet on September 4.
