Kyle Sandilands and rumoured girlfriend Tegan Kynaston spotted at dinner together in LA

Kyle Sandilands and his assistant, Tegan Kynaston, have been spotted dining together just days after denying they were dating.

The recently single radio host, 48, was seen with 33-year-old Kynaston on Wednesday night at West Hollywood haunt, The Ivy.

According to the Daily Mail, the pair stayed at the restaurant for 90 minutes before calling it a night and leaving together.

Just days ago, Kynaston — who was previously Sandilands' personal assistant and is now the director of communications at his company, King Kyle — slammed recent reports that they were an item.

"I know that's kind of been said, but it's completely not true. We just work together," she told the Daily Mail last week. "Nothing to report on. I even thought there might be speculation because I travel with him and stuff as well, but no."

Sandilands' manager Bruno Bouchet also shut down the rumours, telling the outlet on November 12 that romance rumours were "utterly ridiculous". Bouchet claimed the rumours were "hurtful" and "fabricated garbage".

It was on November 5 that Sandilands announced his split from model Imogen Anthony, his girlfriend for the last eight years. The pair started dating in 2011, after meeting at the radio host's 40th birthday.

"A lot people have been hitting us up on social media, a few media enquiries, about my relationship status. We haven't been with each other for quite a few months now. Unfortunately it's run its course," he announced on his radio program, The Kyle and Jackie O Show.
