The model, who is expected to give birth in around three months' time, admitted that she is still slim but with a baby bump.
She told Now: "I'm still a size eight, just with a bump, so I'm going for stretch jersey styles that I can still look on-trend in."
The 24-year-old also explained that she is a fan of high street store H&M.
She added: "I picked up this dress in H&M the day before I wore it on This Morning. I love H&M - it has high street versions of catwalk looks at such bargain prices and it's bang up to date."
