Jo, who was left devastated when the Rolling Stones rocker left her to start a relationship with 20-year-old Russian beauty Ekaterina Ivanova, is embracing life on her own.
Jo said: "I decided the only way to deal with this was to keep my mind off it - get out there and meet new people."
"I'm going to the gym a lot, I'm going to lots of parties - I'm exhausted."
"Actually, the funny thing is, I should be but I'm not. I'm having a great time."
Despite enjoying her freedom, the 53-year-old former model has admitted she misses Ronnie's presence in their marital home.
Earlier this week Jo said: "Lately I've been dreaming of Ronnie. I miss his presence in the home."
"After 31 years together, I'm bound to need time to get him out of my system."
Troubled rocker Ronnie, 61, ran away with Ekaterina to Ireland for an alcohol-fueled trip in July.
He was expected to return to Jo - who he married 23 years ago - after completing a stint in rehab in September.
Instead he continued to romance Ekaterina after being treated for drugs, alcohol and sex addiction.
Last week, Jo was seen wearing her wedding ring at a catwalk show for the London College of Fashion.
