Michelle is a model with Morgan The Agency, having got her career break whilst working in Dublin, Ireland as an air stewardess for the airline Aer Lingus, where she had worked since 1997. She was among twelve well-known females who took part in the "Max Factor Salutes Great Moments in Fashion" show for which she was styled in vintage fashions and hair styles, photographed by fashion Photographer Sarah Doyle and wore a figure-hugging black dress by Louise Kennedy for a portrait which was then sold off at a charity auction. She presented Night Shift, the short lived alternative music show on Channel Six, seven nights per week and also on two weekend afternoons. The decision not to renew the show left both her and Elton Mullally, the co-presenter of the show, feeling "completely bewildered, and absolutely gutted".

Michelle has won the Best Irish Radio DJ category in the Hot Press Annual Poll in 2009 and 2010 becoming the first ever female DJ to do so.

She presented Haiti Aid on 3 February 2010 at Whelan's and The Village in Dublin.

Michelle is originally from County Donegal. She currently spends her time between Dublin and London. She currently resides in London where she gave birth to her first child in 2014.
