Johnny Vaughan, 54, makes a low-key exit from his radio duties in London after welcoming son Milton

He revealed in July that he had become a father for the third time after his partner Vanessa Howard welcomed a son, Milton, following a secret pregnancy.

And Johnny Vaughan cut a low-key appearance as he left his radio duties at the Global Studios in Leicester Square, London, on Tuesday.

The Big Breakfast star, 54, sheltered from the rain in a black padded jacket and dark jeans with navy trainers as he headed home.

Johnny appeared to be having an animated phone call as he stepped out in the British capital.

Since welcoming his third child, son, Milton, in July, the radio DJ has been sharing several sweet updates to his Instagram. 

Posting a picture of him cradling the tot while watching TV in August, he penned: ‘Relaxing with my baby. Happy first month Milton.’

While earlier this month Johnny, Vanessa and Milton enjoyed their first family holiday to Sardinia.

Posing on the beach, he captioned the snap with: ‘Back from Sardinia. This was taken during the two hours of sun we had in 7 days. The deep tan is filter generated. @cala.divolpe.’

Johnny shocked his friends and followers in July after he announced his partner Vanessa had given birth. 

The radio DJ is a father to two adult children Tabitha, 20, and Rafferty, 17, and now has another baby boy named Milton, after keeping the pregnancy a secret. 

The radio presenter welcomed his third child into the world at the Chelsea and Westminster hospital with his girlfriend of three years, Vanessa Howard, 36. 

He took to social media to share the news and was pictured resting his arms on the hospital bed where his adorable newborn was sleeping.

Johnny thanked the staff for helping achieve an ‘immaculate delivery’, as he penned: ‘Welcome to the World Milton Vaughan. 

‘Too proud for words. Thanks to staff of Chelsea and Westminster for an immaculate delivery and Vanessa for being beautiful and awesome. Wow! Just a Wow.’

Johnny and Vanessa have been together since 2017, following the breakdown of his marriage to Antonia Davies.

He split from his previous wife in 2013 after 30 years together and 14 years of marriage. 

Four years later, he was introduced to new partner Vanessa through mutual friends and was quick to whisk her away on a lavish holiday to Marbella in Spain.

Despite the 17-year age gap, the couple have become stronger than ever and have enjoyed multiple trips abroad including a jaunt to Costa Rice in 2019 and a successful skiing trip.
