The girlfriend of radio juggernaut Kyle Sandilands has celebrated her birthday in style alongside the King of the Cross John Ibrahim, his model girlfriend, and convicted drug trafficker Simon Main. Tegan Kynaston rang in her 35th birthday with a swanky Sydney dinner as her inner circle sipped on espresso martinis and posed for photos she then shared on Instagram on Friday night. The glamorous blonde has been in a relationship with the outspoken radio personality since January and has reportedly moved into the KIIS FM host's multi-million-dollar mansion in Woollahra in the city's eastern suburbs. Ms Kynaston is the director of communications for Sandilands' company, King Kyle Pty Ltd, and was previously Sandilands’ personal assistant.
