Andy Murray's fiancée Kim Sears was going through a roller coaster of emotions as she watched the tennis star beat Czech player Tomas Berdych during the Australian Open semi final on Thursday.
So much so she was caught on camera seemingly cursing like a sailor. And now this Vine has gone viral on social media.
Fans immediately tried to guess what it is she's actually saying.
But whatever it is that popped out of her mouth, she's certainly had a big reaction online.
