Peter Andre flew to Puerto Rico to host the pageant which took place earlier today.
He shared a selfie on Instagram, in view of his 1.8 million followers, once he had arrived on the island.
The official Miss World instagram account shared a video of him arriving at the event too.
The Mysterious Girl singer, 49, was also involved in the pageant in 2019.
He had planned to continue hosting duties last year until the event was postponed.
In a statement in December, the pageant said: “Miss World 2021 temporarily postpones global broadcast finale in Puerto Rico due to health and safety interest of contestants, staff, crew, and the general public.”
“The finale will be rescheduled at Puerto Rico Coliseum Jose Miguel Agrelot within the next 90 days.”
In 2020, a film called Misbehaviour about beauty pageants was released starring Keira Knightly.
Misbehaviour is based on the feminists who disrupted the 1970 Miss World pageant in London.
