Former TOWIE star James Argent accidentally let slip the name of pal Mark Wright's nephew's name.
The 34-year-old reality star smiled in a picture posted on his Instagram page, cradling the baby as dad Josh Wright, 32, looks adoringly at his son.
Unfortunately, Arg revealed the youngster's name to the world before Josh and wife Hollie had the chance.
He told his 833,000 followers that the baby's name is Joshua James Angelo Wright.
Under the picture, he wrote: "The first time I met and laid my eyes on baby Joshua James Angelo Wright, I instantly fell in love.
"So pleased for my dear friends @joshwright4444 @holliekanewright. They are going to be amazing parents. #UncleArg."
However The Real Dirty Dancing star apparently realised his mistake, deleting the post before uploading it again- editing out the name.
The tot was born a month premature at the end of February, with uncle and TOWIE star Mark sharing his joy at becoming an uncle.
Mark, 35 opened up about the experience during his radio show on Heart FM, with him referring to his newborn nephew as "absolutely beautiful."
The I'm a Celebrity finalist further discussed becoming an uncle for the very first time, saying: "It's just overwhelming, quite surprising, shocking but in such a beautiful way."
And he revealed that himself and wife Michelle Keegan, 34, had been at his parents' home when they heard the news that his younger brother had become a father.
The presenter explained that the couple - who have been married since 2015 - have been staying at his parents' home whilst in the process of renovating their own home.
He told listeners that his mum Carol Wright, 62, had gone to the hospital amid her grandchild's birth, with Mark, wife Michelle and his dad Mark Wright Sr., 65, remaining at home.
The Strictly Come Dancing alum said that him and Michelle had been lying in bed when his brother announced the baby's birth to the family in a WhatsApp group chat.
The presenter had shared news of his nephew's arrival on Instagram last week, writing in a post: "Welcome to the world little man. Everybody loves you so much."
He added: "Just stick with me son and everything will be alright. So proud of the way you have both handled this early surprise [Josh and Hollie]. Love you both so much."
Another new edition to the Wright family is expected soon, as Mark's sister Jess, 36, is pregnant.
You can listen to Mark Wright on Heart radio on Saturday afternoons from 4pm to 7pm.
