The daughter of Pentecostal pastors’ sighting came three days after Us Weekly claimed she’s postponing her wedding to Carnival Row star Orlando Bloom ‘due to the location they want.’

The on/off couple – who were first linked in January 2016 – rekindled their romance last year after ‘taking a respectful, loving space’ apart from each other in February 2017.

It’ll also be the second time down the aisle for both as the British 42-year-old divorced Australian model Miranda Kerr in 2013 and Katy divorced British comic Russell Brand in 2012.

Meanwhile, 22-year-old Camila bared a single arm and a single thigh in her lacy one-piece and PVC accessories most likely custom-designed by Michael Ngo.
