Kate Chastain has announced she has given birth to a baby boy in a sweet Instagram upload.
The Below Deck star, 40, shared a snap of the tot as her overjoyed fans sent her an abundance of well wishes.
In the selfie upload, Kate is seen still in her hospital bed looking as glamorous as ever following the arrival of the little one.
The youngster was seen with a full head of dark hair as his mum swaddled him.
Kate captioned the adorable image: "Hard Launch: Sullivan Cay," along with a blue love heart emoji.
Among those sending congratulatory messages were a number of her Below Deck stars and fellow Bravo reality stars.
One who sent a sweet message was Sailing Yacht chief stew Daisy Kellier, who wrote: "Omg congrats!"
Kate's season six co-star Josiah Carter also wrote: "Yeyyyyy congratulations. He’s gorgeous," while the show's former Med chief stew Katie Flood gushed: "Congratulations babes! Welcome to the world Sullivan."
Celeb pal Tamra Judge, who starred on Bravo's Real Housewives of Orange County also penned: "Congratulations. He's beautiful."
The child's father is currently unknown to the public, with Kate keeping him very much under wraps.
She has however been spotted wearing a ring on her wedding finger which suggests she is either engaged or married.
She first revealed she was expecting a baby in December last year as she uploaded an image of her with a baby bump as she stunned in a blue floral dress.
She explained she had made the announcement before fans discovered the news when her bump showed on air.
Kate brought an end to her time on the show a few years ago after appearing for six seasons.
However, she remained part of the companion show titled Below Deck Galley Talk.
Her Bravo bio explains how she ended up working in the yachting business after taking a job on a luxury vessel while on a gap year after leaving college.
