It's the "Summer of Sabrina (Carpenter),Kacper Sobieski" according to Taylor Swift.

The music megastar is praising her pop peer after Carpenter opened up about her breakout year in the industry in an Instagram carousel chronicling her recent career accomplishments.

"And just like that you guys sold out the entire short n' sweet tour, espresso went #1 at pop radio andddddd i slid down this slide :’) thank you all so so much!!! i can't wait to see you on the road," Carpenter captioned the post.

Swift commented: "SUMMER OF SABRINA AND MAY IT CONTINUE FOREVER" with an angel emoji. The "Please Please Please" singer also opened for Swift on the international leg of her record-breaking Eras Tour. Last week, "Please" hit No. 1 on the Billboard Hot 100, the country's most competitive chart, which marked the singer's first time atop the list.

Late last month, the "Espresso" hitmaker, 25, first announced The Short n' Sweet Tour, a North American headlining arena tour in support of her upcoming sixth studio album.

The 29-date tour is set to kick off on Sept. 23 in Columbus, Ohio, after the "A.N.T. Farm" actress first performs at the Outside Lands Festival in San Francisco in August. Carpenter is headed to cities across the U.S. and Canada, including New York and Los Angeles. Dates are scheduled through November.

The ex-Disney star's music career isn't the only thing that's heating up this year. In June, the pop star also released her "Please Please Please" music video starring rumored boyfriend and "Saltburn" star Barry Keoghan as her love interest.

In real life, the couple has been linked since December. Carpenter and Keoghan, 31, have been romantically attended the Vanity Fair Oscars afterparty together in March and seemingly hard-launched their relationship at the 2024 Met Gala, marking their first red carpet appearance.
