Controversial Big Brother contestant Marco Pierre White Jnr has confirmed he had split from fiancee Kim Melville-Smith after cheating on her on the show.

The male model, 21, admitted the pair had parted ways following a 'misunderstanding' about the definition of what the 'hall pass' meant while he was on the reality show.

Speaking on This Morning on Monday, the son of acclaimed chef Marco Pierre White admitted he and Kim, 36, were 'just friends' following his wild antics on BB with model Laura Carter.

He said: 'The arrangement we had I was given a hall pass for BB. I was given a free pass to do anything I wanted.... Maybe I did push it to far.

'I'm in contact with her now. We'll see how it goes. Just be friends for the moment.'

Speaking about his relationship with fashion designer Kim - which saw them get engaged just weeks before he entered the house - he claimed he had no regrets over his behaviour on the Channel 5 show.

He said: 'I think Kim's a great person. I don't regret what I did. I shouldn't have done what I did.

'I don't regret anything to do with Laura. I feel guilty. I feel bad. I knew she (Kim) was watching. In the Big Brother house, you do forget sometimes.'

When Marco entered the house on 7 June, he boasted he had been given a 'hall pass' from Kim however, a few days into the show, the fashion designer vehemently denied that 'hall pass' constituted as an 'open relationship'.

She tweeted at the time: 'Fyi I said #hallpass NOT open relationship. I don't watch bb, but I heard this today. Worst thing, I can't even talk to him.'

When co-host Phillip Schofield read Kim's furious tweet, Marco lamented: 'It's confusing me as well.'

Phillip and Holly then suggested that perhaps Marco got engaged to Kim a bit too early, having only dated her for a few months.

His intention to wed Kim was his second engagement this year, having previously been betrothed to commodity broker Jessica Hydleman, who he split from in March.

He conceded: 'Yes I do (get engaged too fast). I don't know why I keep doing it.

'It moved so fast with Kim. She's an amazing person. What I had with her I haven't had with a lot of other people.'

Marco and Laura, 30, shared their first kiss after a few days in the house before going on to have sexual intercourse on the 12 June episode of the Channel 5 show.

Viewers were horrified as they watched the pair indulge in wild foreplay - with Marco even sucking Laura's bare breasts - before they had sex under the covers in the bedroom.

Despite his sexual antics with Laura on the show, Marco admitted he had no plans to see the redhead model when she left the show.

When asked by Holly if he would see her again, he replied: 'I don't think so.'

He also admitted he had spoken to his chef father Marco Snr, 54, who was understandably rather unhappy with some of his son's behaviour in the house.

However, Marco Jnr insisted it was his stories about his wild antics out of the house, rather than his sexual behaviour on the show, that the chef was upset about.

He explained: 'He was a bit upset about some of things I've mentioned on the show, but he is proud of me.

'(It was talking about) my partying and behaviour on the outside world. He's aware of them, but he choose to ignore it.

'I let him down a bit. I feel bad for my sister (Mirabelle, 15).'

Marco Jnr admitted he was upset his mother Mati had given an interview about him over the weekend, claiming her son was 'lost'.

He said: 'I don't feel lost. I'm just a bit wild. Me and my mum - our relationship is very different. We don't really talk as much as I'd like to.

'I don't know why she would say that. I think she's lost and confused.'

He also set the record straight that he had already moved on after he posted a selfie of himself on a bed with a woman's arm lying behind him on Twitter in the early hours of Saturday morning.

He tweeted at the time: 'F**king happy 2 b out wait and see what happens next that house ain't going to be the same f**king dammmm shame. Wait and see what's to come.'

Speaking on This Morning, he explained: 'That was the producer.

'I wasn't in bed with the producer. I went into my hotel room and they were giving me chats... with the producer. She was just sitting on the bed.'

Meanwhile, Kim looked determined to take her mind off her troubles as she enjoyed a day at the polo with Millie Mackintosh in Henley-on-Thames on Saturday.

She understandably stayed away from the live eviction at Elstree Studios on Friday after earlier having lunch with her pal Olivia at The Ivy Kensington Brasserie.

Millie and Hugo reunited having formerly dated in 2011 for six months before a shock cheating scandal tore them apart - after which Millie married her now ex-husband Professor Green.

With such a convoluted love story themselves, the duo were perhaps an interesting place to seek advice, yet Kim used her day out to undergo some counselling from the duo.

She took to Twitter to inform her 7167 followers: 'Just thinking about the advice Millie Mackintosh & Hugo Taylor (cutest couple ever!!) gave me yesterday. Thank you so much, you are so sweet'.

Disbelief: Marco looked flustered when he was quizzed over his very public cheating on his fiancee during his post-eviction interview

During his eviction interview with host Emma Willis on Friday, Marco admitted he may have rushed into things with Laura after he was asked if he thought it was a good idea to start a sexual relationship with another woman.

After watching a clip of their time in the house together, Marco disbelievingly said: 'F*** me, it’s going to get worse.'

When Emma brought up the subject of Kim and his much talked about 'hall pass', a previously unrepentant Marco's resolve appeared to crumble.

'I mean I definitely should have taken my time,' he bashfully admitted.

Shell shocked: Laura, 30, couldn't believe the announcement, and stared open-mouthed as Marco jumped up and headed for the exit after a brief goodbye on Friday

However, Marco stayed defiant and proclaimed he didn't regret anything from his time in the house, but things soon took a turn for the worse as he tried to explain he and Kim were on the same wavelength.

'I mean everything's still cool with her,' he said of his relationship with his fiancée; only to be left shell-shocked when it was revealed she had decided to stay away from the eviction show.

Trotting out his well-worn defense, Marco explained: 'She [Kim] told me I had a hall pass, and it's not an open relationship, but it was in the house. She's a really cool girl.'

Emma felt the awkward tension becoming too much, and ended the interview telling him: 'Go get your phone, go call Kim.'
