The former 'The Only Way is Essex' star has given birth to her and her footballer fiance Andy Carroll's son, and the pair have named the youngster Wolf Nine.
Captioning a picture of the couple - who also have two-year-old son Arlo - with their newborn baby, she wrote on Instagram: "Wolf Nine Carroll You Have Stole Our Hearts 15-11-17 #BabyBoy #Wolfie #MyLittleChubbyCub (sic)"
She also shared a picture of a blue bib with Wolf's initials, W9C, on.

While it's not known why the pair have given their son the moniker Wolf Nine, the number could be a reference to the figure Andy - who is also a dad to Emilie Rose, eight, and son Lucas, five, from a previous relationship - wears on his back while playing for West Ham.
David Beckham named his daughter Harper Seven after the number he preferred wearing during his football career for England and Manchester United.
Billi announced in May that she and Andy were expecting their second child together while on holiday.
Alongside a photograph of the blonde beauty holding Arlo in one arm on the beach and her other hand pressed against her swollen belly, she wrote: "Suns Out Bump Out #BabyCarrollOnTheWay #BabyOnBoard (sic)", followed by a heart-eye emoji.
Billi and Andy, 28, have been dating since the summer of 2013 and got engaged in November 2014.
