World No 1 Naomi Osaka didn't have the best warm-up for the clay court swing, crashing out of the Italian Open in the second round.

That loss to American Jessica Pegula certainly didn't dampen Naomi's spirits.

She traded her tennis shoes for travel sneakers as she and her mum Tamaki Osaka took in the sights and sounds of Rome while teasing fans with pictures of pizzas and gelatos.

'Rome going crazy', Naomi captioned the album uploaded on her Facebook page.
