Barry Keoghan sent a supportive message to his rumoured girlfriend Sabrina Carpenter after she performed with Taylor Swift in Sydney, Australia.
Taylor sang with Sabrina, 24, at her show on Friday night after bad weather meant the younger singer's support slot was cancelled.
Captioning a clip of the duet on Instagram on Saturday, Sabrina wrote: "Nine-year-old Sabrina singing white horse would never see this s**t coming! I love you so so so dearly taylor (sic). always have always will. Thank you Sydney for making me feel so welcome!! See you tonight."
Barry, 31, who has been linked to the Nonsense hitmaker since his split from long-term girlfriend Alyson Kierans, delighted fans by commenting on Sabrina's post with an emoji of a blonde-haired queen.
Taylor's first Sydney concert started late after storms and rain caused Accor stadium to be temporarily evacuated. This meant the support set was cancelled, but Taylor brought the rising star on stage to perform Sabrina's hit White Horse in a mash-up with her own Coney Island.
"My incredibly talented, wonderful, gorgeous, hilarious, genius opening act Sabrina Carpenter!" Taylor said in introducing her pal. "She heroically sacrificed her show which I think is a crime against Sydney and I think it needs to be fixed!"
Earlier this month, Sabrina and the Saltburn star were pictured cosying up at W Magazine's Grammys after-party adding fuel to rumours they are dating after they were seen enjoying a dinner date in Los Angeles late last year.
