Yes so she is! Are there any other mothers on the women's tour, I don't remember if any commentators have mentioned any??! 
I'm not sure how old Kim is but she must be Serena's age mustn't she - or maybe a bit younger.
Anyway it's good news.
Also Simona is reuniting with former coach Darren Cahill which is also good - he coached her when she won RG didn't he? She posted a cute video about him coming back.
Women's tennis is looking pretty good at the mo.
