Barry Keoghan left a sweet messaged for his rumoured girlfriend Sabrina Carpenter after she performed with Taylor Swift at her first Sydney concert.

Taylor sang a duet with her friend and support act Sabrina, 24, at her Sydney show on Friday night after bad weather meant the Nonsense singer’s set was cancelled.

Sharing a clip of the duet on Instagram on Saturday, Sabrina wrote: ‘Nine-year-old Sabrina singing white horse would never see this sh** coming!

‘I love you so so so dearly taylor. always have always will. Thank you Sydney for making me feel so welcome!! See you tonight.’

Barry, 31, sent fans wild as he commented on Sabrina’s post with an emoji of a blonde-haired queen.

‘YES KING GO GET YOUR QUEEN,’ one fan said in response to the signal of support from Barry.

While another wrote: ‘RIGHT!!! SHE IS THE QUEEN.’

Taylor’s first Sydney concert got off to a late start on the night after storms and rain caused Accor stadium to be temporarily evacuated.

This led to the set for support act Sabrina being cancelled, before Taylor finally took the stage a little over 20 minutes after the scheduled start time of 7.30pm.

Taylor ensured that Sabrina still got a show by inviting her on stage for the pair to perform a cover of White Horse together, mashed up with Coney Island.

‘My incredibly talented, wonderful, gorgeous, hilarious, genius opening act Sabrina Carpenter!’ Taylor said in introducing the 24-year-old American singer.

‘She heroically sacrificed her show which I think is a crime against Sydney and I think it needs to be fixed!’

It comes after Sabrina narrowly dodged an awkward question about her rumoured boyfriend Barry.

The American songstress sat down with Nova’s Smallzy’s Surgery this week where she was forced to avoid a question involving the Saltburn star.

Host Smallzy, whose real name is Kent Small, asked the sly question: if Sabrina has seen the psychological thriller starring her rumoured beau.

‘You know, I have…’ the Girl Meets World star answered.

‘Did you love it?’ Smallzy then pressed, to which Sabrina awkwardly replied, ‘Oh, I loved it. Such a good movie… Anyways, I gotta go to the bathroom.’

The interview swiftly moved onto a different topic.

Barry, 31, and Sabrina’s relationship appears to be heating up as of late.

Last week, Sabrina appeared to be wearing the Irish star’s Harvard hoodie as she touched down in Melbourne to open for Taylor Swift during her Australian leg of her Eras tour.

As she arrived at Melbourne Airport, she was greeted by fans, including Tiktokker Tornadothingss who filmed her arrival.

Online sleuths in the comments of the clip made the connection to Barry’s grey university jumper, which he had shared on Instagram previously in a selfie.

‘That’s Barry Keoghan’s Harvard sweatshirt omg,’ wrote one, while another advised ‘yesss Google: Barry Keoghan Harvard sweatshirt and you’ll see a pic of him.’

‘Omg it really is,’ wrote another follower, while another expressed disbelief: ‘No way!’

‘She’s wearing his sweatshirt so random,’ said another fan.

Earlier this month, Sabrina and Barry attended their first public event together after confirming their new romance.

The duo were pictured cosying up at W Magazine’s star-studded Grammys after party.

Sabrina posed on the red carpet solo in a racy sheer top and skirt, but was later spotted partying with Barry inside Bar Marmont in Los Angeles.

The new couple were first romantically linked late last year in December when they were seen enjoying a dinner date in the Brentwood neighbourhood of Los Angeles.

Sabrina Carpenter has ‘never felt uglier’ in Sydney

Last month in January, the two were spotted on a sweet date at an art gallery. A fan had seen the pair at the museum and captured a few images which were later shared on TMZ.

An eyewitness told People at the time that ‘It definitely seemed like a date’ and noted that the pair looked ‘cute’ together and also ‘shared a little kiss’.

The pair reportedly first met during Paris Fashion Week last year in September while at the Givenchy fashion show.

Barry split from his long-term girlfriend, dentist Alyson Kierans, last year amid reports they were rowing about his late night partying.

The two welcomed their first child together – son Brando – in August 2022.

The actor confirmed his split from Alyson while talking to GQ last month.
