She sees herself as anything other than cool, but with music royalty like Bono and Chris Martin among her closest friends, DJ Jo Whiley is about as rock chick as it gets.
Yes she might be a 40-something mum-of-four, but Jo insists she feels as young as she did when she joined Radio 1 back in 1993.
So it might seem strange that she's leaving Radio 1 after nearly 18 years, where she's built up a reputation as a serious music expert and a much-loved voice on the airwaves after helping bands like Coldplay and Biffy Clyro break through.
And not only that, but her move to Radio 2 comes amid rumours she was considered too old to carry on at Radio 1.
Despite her excitement, she's found herself reflecting on the more eventful highlights during her years at Radio 1. So what's her personal favourite?
She laughs. "Having Madonna co-presenting was pretty cool,"
"She was in the studio for an hour and a half just sitting right in front of me. She was all in purple – purple coat, purple knickerbockers and boots – and was necking a massive bottle of cold green tea.
"She gave me a lecture about how I should be drinking that instead of coffee!
"But she was so down to earth. We chatted about our daughters and taking our kids horse-riding. There was no awkwardness between records like there can be. I really liked her." Then there were the guests who were slightly easier on the eye, like Hollywood star Jake Gyllenhaal, who left Jo feeling more than a little flustered.
