January marked three years since Rosie got engaged to Hobbs & Shaw action star Jason Statham.

Rosie and her fiancé have been going strong ever since their first date at the 2010 Coachella Valley Music and Arts Festival in Indio.

Recently, the model described motherhood as ‘magical’ because she claimed everything feels ‘so special and loving’.

She told Harper’s Bazaar: ‘It sounds so clichéd, but it’s just been the most magical experience. Everything feels so special and sweet and wholesome and loving and then at the same time it’s been life-changing, and my focus is now this person; this is what I want to do.

‘This is what I want to pour my heart into now.’ She catches herself sounding too serious. “Hashtag blessed, right?”‘
