The fashion designer, 45, uploaded an adorable picture of her brother’s new arrival in view of her 25 million Instagram followers. The pictures showed the baby lying on a lilac blanket, snuggled up to a cuddly mouse toy. Victoria Beckham also unveiled the name of her newborn niece, writing in the caption: “Baby Tabatha Adams.” She went on to extend her congratulations to the couple, saying: “Congratulations @christianadams_79 @emma.adams17. Kisses X.”
Victoria’s son Romeo Beckham, 16, joined her in celebrating the addition to the family, sharing the picture of Tabatha with his own two million followers on his story.
Christian and his wife Emma tied the knot in December 2017 and are already parents to three boys.
The Beckhams attended the ceremony, with their daughter Harper, seven, taking on the role of flower girl.
At the time, ex-Spice Girls star Victoria shared a picture from the wedding, showing her husband David Beckham, 43, and their son Brooklyn, 20, looking dapper in matching suits.
The pair posed with their hands in the pockets of their navy three-pieces, with Victoria captioning the picture: “My handsome boys!”
She also uploaded a video of the happy couple’s first dance, filming them swaying on the dance floor from a balcony above.
Earlier that year, she shared a sweet snap of her brother’s family at the christening of their youngest son.
All five of them could be seen smiling for the camera in the church, with Christian’s famous sister writing on Instagram: “Beautiful family day today. Otis Adams’ christening. Love u christianadams_79 @emma.strafford.”(sic)
Victoria and her former England captain husband are themselves parents to four children.
Shortly before they wed in 1999, the A-list couple welcomed their eldest son Brooklyn.
Romeo was born a few years later, with Cruz, 14, being the youngest of the three boys.
David and Victoria added to their brood once more when Harper was born in 2011.
Victoria is one of three children, with brother Christian and sister Louise.
She previously opened up about her family life growing up, telling Vogue: “My family brought me up telling me I could achieve absolutely anything.
“Whenever I said, ‘I can’t do it,’ my dad, he just wouldn’t hear it.
“He’s say, ‘What do you mean you can’t do it? Why? Why?’ And so I do that to my own children as well.
