The presenter looked sensational as she showcased her post pregnancy body, modelling her new online fashion collection for Very.co.uk.
The blonde beauty, 31, has been tweeting about her sleepless nights looking after her teething baby, but there were no signs of any exhaustion as she returned to work.

She shows off a dip-dye fuschia dress with billowing angel sleeves with her long hair flowing over her shoulders in one image, while in another she wears a floaty purple dress with matching heels.
In a bid to shed the pregnancy pounds, Fearne has been following the Honestly Healthy diet. Victoria Beckham and Millie Mackintosh are fans of the diet, which involves eating alkaline foods in an effort to keep the body's pH between 7.35 and 7.45.
This is Fearne's latest collection for online retailer Very.co.uk. The clothes range from £22 to £69.
Jon Owen, the retail director of Very.co.uk, said they were delighted with their continuing collaboration with the star.
"Our customers always respond well to Fearne's collection as she is such a strong icon and great ambassador for her range," he said.
"Fearne's AW13 collection gives our customers access to her signature style, and the ability to make it work for them."
Fearne welcomed her first baby, Rex, with fiancé Jesse Wood, back in February.
She has kept fans updated with her little one's progress over the past few months, sharing images of the baby boy. She also tweeted about his teething. "Spent 45 mins at 2am searching for calpol for teething Rex. Had packed it away in one of 20 boxes as we are redecorating our kitchen. #fun," she wrote.
She also recently unveiled a homeware range with Very.co.uk.
Fearne will return to her role as a DJ on Radio One's mid-morning slot from September after Sara Cox has covered her maternity leave for the station.
