The model had her six-month scan at the weekend
Katie‘s baby bump was on full display as she strolled to the hospital in East Grinstead, West Sussex in a pair of grey leggings and a cropped blue T-shirt.
Learning the sex of her little one was ‘bittersweet’ for Katie.
Mum-of-four Katie married Kieran after a whirlwind romance in January 2013 and they welcomed their son Jett Riviera last August.
Just days after revealing that she was pregnant with their second child together, she Tweeted that Kieran had been having a seven-month ‘full blown sexual affair’ with Jane, 48.
Despite her heartbreak, Katie – who’s also mum to kids Harvey, Junior and Princess – is trying her best to ensure nothing affects the health of her unborn baby.
‘For days after she found out about Kieran she could barely stomach food, she was so heartbroken. But she’s determined now to stay fit and healthy for her little girl,’ a source tells The Sun.
‘She just wants things to be as normal as they can possibly be for the rest of the pregnancy. She was so excited to find out she’s having another daughter.’
