Proud Judy Murray has spoken about son Andy Murray's engagement
"I'm so happy that Andy has got engaged, it was very exciting when it happened. I'm thrilled to bits about the engagement.
"He was very traditional and called Kim's parents beforehand. He is very traditional like that," she said, before adding, "I definitely won't be dancing at the wedding, that's for sure."
She continued, "It's going to be next year, maybe October time. I think he just wants to start being engaged before he starts doing all that.
"I think it's for them to choose exactly what they want to do for their wedding. It's completely up to them. I don't know if the wedding will be in Scotland."
Andy Murray and Kim Sears announced their engagement in November
Judy might have ruled out dancing on the big day – but it seems Andy has already has a few moves up his sleeves. "He was best man at his friend's wedding last Saturday so he asked me to show him the Waltz in case he had to dance with one of the bridesmaids, so I have actually shown him the very basic moves of the Waltz," his mum revealed.
Andy, 27, and artist Kim, 26, announced their engagement in November after nine years together. Judy has described Kim as "the best thing to happen" to her son.
The couple met at the US Open in 2005, although their romance did not become public knowledge until 2006, when Andy ran to kiss Kim after winning his first senior title.
