Australian beauty queen Gabby Epstein alarmed fans on Wednesday when she debuted her very dramatic weight loss.

The lingerie model, 29, who is currently based in Los Angeles, shared a few snaps of her extremely lithe frame to Instagram, prompting a tide of concerned comments.

Long-time fans of the blonde bombshell said Gabby’s latest pictures, in which she flaunted her taut figure in black lingerie, were ‘scary’ and ‘concerning’.

A third added: ‘Yo dawg people are genuinely worried about you. No one is trying to be mean, we’re just concerned.’

Someone else said: ‘Yo I’ve been following her since 2015 and I promise you she is not okay right now.’

Gabby was quick to hit back at the comments about her body, saying she managed to drop so much weight because ‘all I do is workout’.

‘Please if you don’t have something nice to say, you don’t have to say anything at all xoxo,’ she added.

Despite the slew of negative comments, many fans rallied around the Playboy model and left messages of love and support.

‘Babe you are so beautiful more beautiful than anything on this planet,’ one person wrote.
