Kyle Sandilands’ wife Tegan Kynaston  goes solo as she celebrates their son’s first birthday with a family gathering at Parsley Bay Park

Tegan Kynaston was enjoying a day out in the park with her son and family on Friday. 

The wife of Kyle Sandilands took the couple’s little boy Otto to Parsley Bay Park in Sydney to celebrate his first birthday. 

The 37-year-old wheeled little Otto along in a pram across the grass as she headed for a nearby bench. 

Tegan, who went solo to the outing with Kyle staying home, dressed casually in a black cropped jumper that showed off a hint of her midriff. 

She added a pair of dark blue jeans and sneakers, while adding a pair of designer sunglasses.  

The socialite appeared to have on minimal makeup while wearing her blonde hair down around her face.  

She met some loved ones in the park, with the group cooing over Otto as he toddled around on the grass.  

Tegan also stopped into a nearby café for a drink, bringing her baby boy along with her. 

It comes after Kyle became emotional live on his KIIS FM radio show on Friday as he celebrated his son Otto’s milestone first birthday. 

The radio king, 52, walked into the show’s Sydney studio and was greeted by balloons and cheers from producers to mark the occasion. 

He then walked in to record the show and saw sweet pictures of Otto on the screens. 

‘Oh that’s when he was born there, look at him,’ an emotional Kyle said in one clip. 

‘Look at the baby, how exciting, his first birthday!’ Godmother Jackie O said. 

In a sweet gesture, Kyle said in a video that listeners could call up and get free presents for their kids. 

‘If your kids call the station today, instead of my son getting his birthday presents, we’re giving the presents to your children,’ Kyle said. 

‘If you say, I want a rocking horse, done, there’s no limits.’ 

Images of Otto were shared on KIIS FM and Kyle and Jackie O’s social media pages, including a sweet picture of the tiny tot on a swing with a crown Photoshopped over the image. 

‘Happy 1st birthday Otto!’ the post read. 

Earlier this week, Kyle revealed he is spending a whopping $25,000 on son Otto’s upcoming birthday party. 

Kyle revealed he even got a party planner for the day with 24 children and 38 adults invited to celebrate the youngster.

‘It’s only $25,000,’ Kyle said. ‘It’s a watered-down type of party.’

Newsreader Brooklyn Ross was in disbelief asking Kyle if that claim was a ‘joke’ while co-host Jackie ‘O’ Henderson sarcastically called the celebration plans ‘low-key’.

Kyle said the exorbitant number did not include all the other party supplies that wife Tegan Kynaston has purchased for the party.

‘Like the lollies, the bonbonierri, and the plates and all these weird tablecloths. These are eight foot tablecloths,’ he said.

Kyle joked he was under strict instructions from Tegan that he has to come out of his room to ‘engage’ with guests during the festivities.

‘I said ”do I have to come out of my room?” and Tegan said ”yes”’ Kyle explained. ‘I’m supposed to be engaged with the visitors.’

Kyle has been besotted by Otto in his first year of fatherhood.

The shock jock gushed over the tot during an interview with Daily Mail Australia in October last year.

‘I used to watch hours and hours of TV, and now I just sit there looking at him and he’s really been a joy,’ he said.

‘I’ve just been sitting at home the whole time which I’ve enjoyed. I’m at home now more than I was with lockdowns, so we’re loving every second of it.

‘I’m pretty happy actually. I can’t imagine being any happier.’

Kyle admitted he never dreamed of having children, but now he’s ‘thrilled’ that he decided to take the plunge and become a dad.

Following the birth of son Otto, Kyle tied the knot with a no expense spared ceremony at the Swifts mansion in Darling Point, Sydney.

Kyle reportedly splashed $1 million on the event with the likes of Prime Minister Anthony Albanese and leading showbiz figures there.

Before the wedding, Kyle revealed he had lost an impressive 20kg on a health kick.
