"I would do anything to have that experience of being pregnant again," the 32-year-old TV and radio presenter told Red magazine. "Oh, when I was pregnant and huge, I felt the most amazing I've ever felt.
"The day after I gave birth, I remember looking in the mirror. I probably looked horrendous. And I felt like I looked the most beautiful I had ever looked."
But Fearne did admit that motherhood isn't all plain sailing, as she feels torn between spending time with Rex and getting on with her work.
"I'll be interviewing Coldplay, feeling bad for being there," she said. "There's this little tap on the shoulder, your subconscious saying, 'Don't enjoy this too much, you should be at home'."
Regular Glastonbury attendee Fearne made it to the festival this year, but last year she and Jesse decided to stay home because 'it would play havoc with the breastfeeding schedule,' even though it meant missing out on seeing Jessie's father, Ronnie Wood, perform with The Rolling Stones.
Fearne and Jesse's family also includes his two older children - Arthur,12, and Lola, seven, - from his first marriage to Tilly Boone. Fearne describes their home life as 'mad at the weekends,' but says she can't imagine her life any other way.
