Montana Brown's eulogy at Mike Thalassitis' funeral featured a stark warning for all the reality stars in attendance.
The Love Island star, who was close friends with Mike, stood up during the service to give a speech about her friendship with the former footballer.
Outside the church, Montana was seen flashing a copy of her eulogy in clear view.
It revealed she ended by addressing all the reality stars who had attended the service, including castmembers from several seasons of Love Island.
Montana warned them they need to learn from this tragedy and change their ways to be "nicer, be kinder, more genuine" and she begged them to "check in on each other".
She said: "The whole nation was shocked by this, and this isn't something you forget.
"I'm looking at everyone right here and asking you to change yourself, change how you live your life, change how you love your loved ones, and also change how you treat strangers.
"I can see a lot of reality faced in the room, please do not let this pass you by.
"It's so hard, the rejection, the competitiveness, the need to constantly look ok on social media.
"So let's learn from this. We're all in the same boat. We all go through the same stresses.
"Let's just be kinder, be nicer, more genuine, let's check in on each other, life's too short."
She also spoke about how much she loved Mike and the tragedy that he took his own life.

Montana said:"Mike I truly believe you exhausted every avenue to avoid this outcome as I know you knew you were loved by so many people.
"You're kind, you're generous, and sometimes very lairy, but that's the Mike we all cherish and love. I know there's people in this room who'd give anything to have you back.
"You were so misunderstood, and I feel privileged to have been your friend..."
Other stars at the funeral today included Love Island host Caroline Flack, WAG Rebekah Vardy, and Love Islanders Zara McDermott , Ellie Brown , Samira Mighty , Alexandra Cane and Amber Davies.
After it was over, Ellie took to Instagram to tell Montana she was taking the message onboard.
She wrote: "The most beautiful and heart-breaking service. A day I will never forget and so many lessons learnt.
"Well done Montana... and all of Mike's brave friends and family.
"Sending you so much love and strength. Rest in peace Mike we all miss you. You are so loved."
Mike was found hanged at a park in Edmonton, North London three weeks ago aged just 26.
Mike is said to have battled depression in the months before his death, and had turned to therapy and self help books.
