Kyle Sandilands and his girlfriend Tegan Kynaston fly to Los Angeles

Kyle Sandilands and his girlfriend, Tegan Kynaston, put on a united front on Sunday following a turbulent few weeks.

The couple were spotted at Sydney Airport en route to Los Angeles, two weeks after Tegan pleaded guilty to assaulting a police officer in Sydney.

The blonde appeared to be in a good mood as she walked ahead of her boyfriend in pair of skimpy denim shorts and a black and white cardigan.

Tegan, 34, also donned a pair of comfortable DKNY sneakers for the flight.

She slung a fringed bag over her shoulder and accessorised her look with a pair of oversized sunglasses.

Meanwhile, Kyle dressed casually in a black T-shirt, baggy shorts and a body warmer.

The 48-year-old radio host slicked back his grey hair, and also wore sunglasses.

The couple – who confirmed their long-rumoured romance on New Year’s Eve – had plenty of luggage, which airport as staff helped them unload outside the terminal.

Kyle recorded his KIIS FM breakfast show live from a studio in LA, while his co-host Jackie ‘O’ Henderson broadcast from North Ryde, Sydney. 

The sighting comes amid a challenging time for Kyle and Tegan.

On January 21, Tegan pleaded guilty to slapping a policewoman during a public spat with her boyfriend, but will seek to have her case dealt with under mental health provisions. 

She was charged with assaulting police after slapping the female officer in Bondi Beach, Sydney, on Saturday, December 7.

During the hearing, it was revealed that Tegan had taken three grams of cocaine and was threatening self harm before she slapped the policewoman in the face.

She faced Waverley Local Court on January 21, where her solicitor Greg Goold entered a guilty plea to assaulting a police officer in the execution of her duty.

Mr Goold told a registrar his client would seek to have the matter dealt with under Section 32 of the Mental Health (Forensic Provisions) Act.

If the matter is dealt with under the Mental Health Act, it may not lead to a criminal conviction.

Tegan is already on a bond for possessing cocaine after being caught with about half a gram of the drug outside a Surry Hills pub in March 2018.

That matter was mentioned in court.

Tegan – who is director of communications for her boyfriend’s company, King Kyle Pty Ltd – began dating the shock jock following his split from ex-girlfriend Imogen Anthony.

Kyle announced his split from Imogen, 28, whom he had dated for eight years, live on air on Tuesday, November 5.

‘We haven’t been with each other for quite a few months now,’ he said at the time. ‘Unfortunately it’s run its course.’

Tegan is due back in the same court on April 14.
