Dressed in simple jeans and jumper, the artist dressed down for his match against Jo-Wilfried Tsonga at the US Open in New York.
We love her 'Dreamy' top!
And, of course, her amazing hair was as perfect as always…
It was a good day for Kim who cheered on Andy as he won in straight sets (7-5 7-5 6-4) to reach the US Open quarter finals.
Andy isn't the only member of the Murray household getting in the competitive spirit right now: his tennis coach mum Judy has been announced as a competitor on this year's Strictly Come Dancing.
Judy said: "I'm a huge Strictly Come Dancing fan but a total armchair dancer. It's going to be a big challenge for me and for whoever has to dance with me but I absolutely can't wait to get started!"
Hopefully we'll see Kim, her amazing hair and Andy in the audience later this year!
