ANTONIA SALT risked a red flag as the grid girl went topless in an Instagram video.

The model is equally popular for parading around a boxing ring as she is for her trackside role.

But her latest risque offering on social media might have raised a warning flag rather than a scorecard.

Antonia shared a clip of herself in just leggings and socks.

The motorsport influencer then “bared right” as he turned her back to the camera to put on a short, tight top.

She burst into giggles when she slipped into the long-sleeved T-shirt.
