Watch: Love Island 2021 trailer
The married couple, who voice and present the ITV dating show respectively, will be back on our screens at the end of the month with brand new singletons looking for love.
Announcing their arrival at the luxury villa which plays home to the series, Stirling posted a photo of two water bottles bearing his and Whitmore's names.
Behind the bottles is a clear blue sky and palm trees, signalling they had landed in the Spanish resort.
He wrote alongside the picture: "Not long now..."
Love Island is due to return to our screens at the end of June, returning to its 'home' of Mallorca for the first time since 2019.
The 2020 series, the first-ever winter version of the show, was filmed in South Africa across January and February, before the coronavirus lockdown.
As a result of the pandemic the planned summer series was scrapped due to the logistics of filming abroad.
This is Whitmore's second series hosting Love Island, having taken over from Caroline Flack last year.
Comedian Stirling has been with the show since its launch in 2016, becoming famed for his cheeky commentary on the contestants' antics.
This year's cast is yet to be announced, but an ITV boss has stated they're looking for 'more diversity and inclusivity', potentially including bisexual contestants.
However, they added that gay contestants presents a 'logistical difficulty' within the confines of the show, which sees couples pair up and try to remain together.
TV’s commissioner Amada Stavri told Radio Times: "In terms of gay Islanders, I think the main challenge is regarding the format of Love Island.
"There’s a sort of logistical difficulty, because although Islanders don’t have to be 100% straight, the format must sort of give Islanders an equal choice when coupling up."
Love Island arrives later this month on ITV2.
