Jesse and Fearne, 33, married last year after welcoming their baby son, Rex.
When Fearne first started dating Jesse in 2012 she had to adjust to being a step-parent to Jesse’s children Arthur and Lola.
Jesse was previously married to ex-wife Tilly Wood- the mother of his eldest children- between 2003 and 2011.
Luckily, Fearne bonded with Jesse’s offspring and the family is now a happy unit.
She told This Morning: "I've got two step-children. I was 29 when I met my husband it was quite an induction to being a proper parent. Rex adores and idolises them."
Fearne also spoke about juggling her busy career as a Radio 1 presenter along with bringing up her young son, who turned 2 at the weekend.
She said: "My husband is away a lot, he's in a band, we have to be very militant, my cousin is our nanny, we are super organised.
"Any working mum takes a step back and thinks throughly about what choices they make, for me family comes first."
Fearne will be celebrating her fellow mothers at this year’s Tesco Mum Of the Year, where she has been made ambassador.
