The Duchess of Sussex is already fifteen weeks pregnant, according to sources.

The 'Royal Bump' has made its first appearance since the Palace announced that the newlyweds are expecting their first child in Spring 2019.

After touching down in Sydney, Markle looked as radiant as ever in a white sleeveless shift by Aussie designer Karen Gee. The fitted sheath is called the 'Blessed dress' - how fitting.

Mother-of-five Gee told the Sydney Morning Herald that her website crashed in the moments after Markle stepped out at Admiralty House with Australia’s Governor General Peter Cosgrove and his wife, Lady Lynne Cosgrove.

Gee told the paper she was "so proud, particularly because I am not a world recognised brand".

She also laughed that all the traction has crashed her website - as people clamoured to get a closer look at the ‚ā¨1,100 frock.

According to Royal style bloggers, Markle was also wearing jewellery that belonged to Princess Diana.

The couple also went to the Taronga Zoo, as the zoo named two koalas after them as a "wedding present".

Their 16-day Southern Hemisphere trip will be a busy one: they're expected to make roughly 76 appearances in Australia, Fiji, Tonga, and New Zealand.

You know what that means... so.much.maternity.wear.
