Dancing with the Stars is set to be rocked by a shock kissing scandal on Sunday’s grand finale.

According to an eye-witness, 63-year-old funnyman Shaun Micallef is set to go one step too far with host Chris Brown on the glittering final dance-off.

A source revealed exclusively to Daily Mail this week that during filming Micallef planted a kiss on the lips of Brown in front of the studio audience – leaving the famed TV vet lost for words.

The moment came in a post-dance interview on the Sky Deck during the Dancing With the Stars grand finale.

Brown, who has been good humoured about the comedian’s relentless kidding around all season, was suddenly stopped in his tracks when Micallef appeared to ‘proposition’ him.

‘We should get some lunch after this, is this really happening?’ Micallef joked as Brown reviewed the scores.

‘He then went in for a kiss and they locked lips, leaving Brown in shock’, the source revealed. ‘He seemed to lose all composure for quite a while after that.’

Micallef then turned to the camera, recalled the eyewitness, and said, ‘That [kiss] is not for Channel Seven.’

A spokesperson from Seven confirmed the ‘interaction’ took place, was not cut from the final edit, and will air during Monday’s episode when Shaun and his dance partner Ash-Leigh Hunter strut their stuff in the Grand Finale.

It comes after fan favourite Osher Günsberg was shown the door during a dramatic episode of Dancing with the Stars earlier this season.

Taking to the ballroom with a Tango routine backed by David Bowie‘s 1980 hit Fashion, the TV host put in a feverish performance that failed to impress the judges.

Taking his cue from the evening’s ‘Kings and Queens of song’ theme, judge Craig Revel Horwood did not mince words when delivering his verdict.

‘Well that was a right royal mess! I don’t know what that step was, coming down the ramp, darling, but it was fumbled…’ Craig began, but a furious Osher interrupted.

Visibly annoyed, Osher snapped, ‘Would you like to try going down that Perspex ramp in those heels, sir? You’re more than welcome to show me.’

He continued to rage: ‘But I need you to be doing it in a tango step while the person next to you is on one foot kicking, and you’re holding their momentum against you. After you!’

Craig seemed taken aback by the fiery exchange, replying to a fuming Osher, ‘That is not my job’.

He then continued on with his critique despite the tense atmosphere, which had host Sonia Kruger visibly shocked.

‘It was completely erratic,’ Craig said, after dismissing Osher’s remarks.

Craig told the frustrated TV personality, ‘You were making mistakes left, right and centre.’

Fellow judge Mark Wilson did offer Osher some words of encouragement, telling him that he admired his determination to improve his dancing skills.

However, the final score was a dismal 15 points and Osher was sent home.

Dancing with the Stars competitors are now set to head into the Grand Finale on Monday.
