Jodhi Meares' breast boost

J *odhi Meares *has sparked speculation she may have gone under the surgeon's knife.

The fashion designer retreated from the public eye last month after her fiance, Noiseworks musician *Jon Stevens *, was charged with assault, reportedly after an explosive fight between the couple.

But now she has re-emerged on Instagram, posting a bikini snap, above, in which she appears to show off noticeably fuller cleavage.

Some have suggested Meares may have had a breast enlargement, comparing the photo to images from her younger years as a bikini model where she sported a significantly flatter chest.

While the 42-year-old has made several posts to her profile since the fight, including inspirational quotes and images promoting her label The Upside, this week's snap is the first one of her since early February.

Stevens will face court in May over the Sydney incident, which reportedly broke out after Meares discovered messages on his phone from an ex-girlfriend.

It's the latest controversy to dog the former wife of *James Packer *. She was charged with drink-driving last July and subsequently barred from getting behind the wheel for 12 months.
