Taylor Swift is powering through her “Cruel Summer” … as the singer has reemerged after a thwarted terror plot saw her “Eras” tour stop in Vienna canceled last week.

The pop star stepped out in London Monday for a celebratory evening in honor of her tour staffers, where she treated her employees to a night of fun at a members-only club called Annabel’s.

Taylor wore a serious expression as she made her way into the hot spot … but looked as chic as ever in a plaid 2-piece set, which she paired with chunky pea green platforms.

The singer made it clear she wasn’t hiding after 3 male teens were arrested for planning a mass murder plot at the Ernst Happel Stadium, where Taylor was scheduled to perform 3 sold-out shows.

Taylor’s shows were expected to bring in more than 200,000 people … who the alleged plotters planned to target with bombs, knives and more.

The singer has not canceled her tour, however … and is in London again as she’s performing 5 additional nights at Wembley Stadium, where she performed 3 shows in June.

Summer 2024 had already been a heartbreaking one for Taylor prior to the terror plot … after a mass stabbing at a Swiftie-themed dance class left 3 young girls dead in Southport, England.
