After former Big Brother housemate Mark Byron exclusively told us that tantrum queen Nikki Grahame stormed out of a celebrity charity event in Vauxhall last Thursday after spotting BB16's Nick and girlfriend Harry Amelia arriving together, Mr Henderson has opened up to discuss what really happened between the pair the night of the infamous kiss, and after too.

Early last week, Nick and Nikki were spotted leaving an exclusive London event together in a taxi.

Nick, 20, told us how the pair came to go out together: "Nikki dropped me a text the night I came out [of the BB house] to say well done, look forward to seeing you.

"I gave her a call the next day and we caught up and she invited me to the event."

The BB star told us: "I just went round to her place in London for pre-drinks."

Nick was also joined by Nikki's agent.

So what about the picture that surfaced of the pair sharing a kiss at the Attitude party?

"This is me being totally honest, we did share a kiss. We did it in the photo booth, and we did have a little kiss afterwards, which Harry is totally aware of and it was a complete disaster, I mean a huge mistake."

Apparently Harry wasn't all that impressed either: "Obviously she was annoyed, she said everyone makes mistakes and you’ve been an idiot. And I was. She said we can move on from this."

A party insider told us: "They looked close all night, you could tell Nikki was really into him."

We asked Henderson if he should have realised it was time to head home after a naughty snog with the BB Legend: "Oh my God, in hindsight of course I should have. Rabbit in headlights with everything, it was all very exciting and I was all sort of lost in the moment.

"In hindsight, what I should have done is absolutely left the party."

He continued: "Reflecting back, I’ve learned a lot of lessons from that and it was my first time doing stuff like that."

When quizzed on whether or not Harry and Nick had, ahem, sealed the deal by this point, Nick explained: "That's quite private."

So we questioned if kissing Nikki was considered cheating: "No, me and Harry have spoken about this and what Harry said is, 'You’ve made a mistake you’re an idiot.'

"We’ve pretty much moved on from it."

Great.

I've not seen this much media attention for former housemates in years!
