Zara McDermott will finally disclose the details of when she cheated on boyfriend Sam Thompson.
Intimate details of the night of passion will be unravelled on Monday night's explosive episode of Made In Chelsea.
After coming clean about her infidelities, heartbroken Sam called it quits on their whirlwind relationship.
Now, following a string of public pleas to get her beau back, Zara will dish the dirt to her Made In Chelsea pals including Strictly Come Dancing star Jamie Laing.
Shocking scenes capture the reality TV siren, 23, breaking down into tears as she told Jamie she cheated on his best pal.
While the pals are sat around at a lavish dinner table, Zara confessed: “I did something really bad around a year ago. I slept with someone!”
“When it happened, I genuinely thought that me and Sam were going to break up inevitably. I just thought we were hanging on by a tiny thread and we're going to break up.
She continues: “Then he turned around and said he wanted to make it work with me.”
Clearly stunned by her announcement, Jamie rushed to put his head in his hands as he sitalongside his long-term girlfriend Habs.
After Zara’s confession finally sinks in, Jamie sarcastically clapped back: “That's not very sweet!”.
He then goes on to tell her she shouldn’t make excuses for her behaviour before reiterating that the fact that his loyalties will always lie with his friend Sam.
When stunned Habs asks Zara if she and Sam are still together, the puffy-eyed star explained their relationship is in deep water since she came clean about her actions.
Zara replies: “Yeah but I don't think for much longer!”.
Zara and Made in Chelsea star Sam were together for 16 months before they split.
Sam kicked her out of his flat when he discovered what happened.
Zara has been back living with her parents in Essex.
She has tried several times to win back her beau with gushing social media posts and apology letters.
Made In Chelsea returns tonight at 9PM on E4.
