Judy Murray has thanked people for their well wishes on the birth of her first granddaughter.
Tennis star Andy and wife Kim became parents to a baby girl on Sunday with his agent saying on Tuesday that the family "are doing well".
No details have yet been revealed about the child's name but news of the birth prompted an influx of good wishes from fellow sports stars and members of the public.
New grandmother Judy also received warm messages online and responded on Twitter on Wednesday saying: "Thank you for all the baby messages.
"Thrilled to bits. Love from Granny."
Andy and Kim, who live in Surrey and are both 28, married in Murray's home town of Dunblane in April last year.
Before the Australian Open he described the wait for the birth as "very, very exciting'' and made it clear that he would have cut short his first grand slam of the year and flown home if the baby had arrived earlier than expected.
He said: ''For me, my child is more important to me, and my wife is more important to me than a tennis match.''
Murray did make it to the final and tearfully told Kim she was ''a legend'' and that he would be on ''the next flight home'' after being beaten to the title by Novak Djokovic.
