Every inch the proud mother, Terri wrote on Instagram: ‘Today our beautiful, sweet Coco turned 5!! Happy Birthday to our kind, snuggly, funny, smart and curious angel. We love you so very much.’

Terri welcomed Coco to the world with boyfriend Clark Mallon back in 2015, describing her daughter as a miracle baby. 

The TV star had previously been told by doctors she may not be able to have a family after she was diagnosed with systemic lupus when she was 15, and then suffered a burst bowel due to peritonitis in her early 20s.

 She previously told the Brampton Guardian: ‘That was a very harsh realization to face when you’re so young. 

‘I guess I spent a lot of time throughout my 20s and 30s wondering whether it would even be able to happen. 

‘Now I feel so lucky to be a mummy.’ 

Along with her TV career, Terri is also known for previously being in a relationship with music mogul Simon.  

In a previous interview with DailyMail.com, former model Terri claimed Coco and Eric are ‘boyfriend and girlfriend’. 

She revealed: ‘Coco and Eric are like this. They are really good friends we go on lots of playdates. Eric calls Coco his girlfriend, so it’s scary.’

Terri and Simon were an item for eight years before their split, with the music mogul rumoured to have given her a £6 million ‘parting gift’. 

He then went on to become engaged to Afghan-born make-up artist Mezhgan Hussainy in 2010, but they split in February 2012.
