After traveling around Mauritius, Catriona Gray and Sam Milby are continuing their adventure in East Africa!

On Thursday, the Miss Universe 2018 titleholder shared breathtaking photos of herself with boyfriend Sam as they visited Nairobi National Park in Kenya.

Clad in COS-designed clothes as they posed in the grassy field, Catriona wrote, "Saw the beauty of Africa first hand at the Nairobi National Park."

In September, Catriona announced that she would be attending Miss South Africa 2021 as its host alongside Miss Universe 2019 Zozibini Tunzi.

The pageant, which will be held on Oct. 16 at the Grand Arena in Cape Town, will also be attended by Miss Universe 2015 Pia Wurtzbach as one of the members of the selection panel. – Kaela Malig/RC, GMA News
