Taylor Swift Dances With Pals at Calvin Harris’ Vegas Show

Taylor Swift danced the night away with some of her closest friends at boyfriend Calvin Harris’ show at Omnia nightclub in Las Vegas on Friday, March 18.

Swift, 26, was spotted cheering on the hunky DJ, 32, with supermodel BFF Karlie Kloss and her twin sisters, Kimberly and Kariann Kloss, who were also celebrating their 21st birthday.

The “New Romantics” singer looked gorgeous in a charcoal sequin dress as she danced along to some of Harris’ biggest hits, including “Summer,” “How Deep Is Your Love” and Rihanna’s “We Found Love.” She was also joined by members of the band Haim, Serayah, her younger brother Austin Swift and YouTube star Todrick Hall.

The happy couple, who recently celebrated their first anniversary, just returned from a romantic tropical vacation. Swift shared a series of photos from the getaway on Instagram on Tuesday, March 15, including a rare PDA snap of them kissing on the beach.

“Taylor Swift + Adam Wiles,” she captioned another shot of their initials in the sand.

“She’s head over heels,” a source previously told Us. “She hasn’t been in love like this before!”
