The pregnant musician launched into a furious rant on Twitter after having her car struck yesterday evening, posting the individual's vehicle registration number on her profile before stating: "I'd like to thank you for punching my car window with my daughter in the sitting in the back. Big man (sic).
"Ava was upset as didn't understand what was going on. I just know if I was a 6ft man, he would never have gotten out of the car so I ll name n shame him myself."
Following an outpouring of support from her online following, including celebrity friends Emma Bunton, Denise Van Outen and Lauren Laverne, Klass added: "THANK YOU, ALL of you for checking on Ava n me. Coward of a man."
In her most recent message tonight, Klass confirmed that she had reported the incident to authorities and hit back at those who criticised her decision to publish the alleged perpetrator's information.
"To those asking, Avas ok n I get my crime number in 48 more hours! To those offended I posted a nethanderals reg, look away now," she wrote, before adding the registration number again.
Klass was cautioned by police last year for brandishing a knife at a group of trespassers in her garden.
