Kim Sears, the fiancée of Andy Murray, has hit back at her critics after she was caught on camera swearing by wearing a 'parental advisory' t-shirt at the Australian Open final.

Sears was spotted during Murray's semi-final victory over Tomas Berdych aiming what appeared to be a foul-mouthed rant in the direction of her partner's opponent and entourage.

She was criticised for appearing to refer to Berdych's Czech nationality.

After the match Murray defended his long-term girlfriend, explaining: "In the heat of the moment, you can say stuff that you regret.

"When there's a lot of tension surrounding something, which you created, it's completely normal that the whole first set everyone was tight."

Now Sears has hit back in her own way by wearing a t-shirt that reads "Explicit content / Parental advisory".

As well as being a cheeky riposte to those who criticised her it might also manage to make the cameras think twice before focusing on her at the crucial moments. But probably not.
