While her mom kicked off the introduction, Suri helped by happily saying the pop star’s name right on cue.
“She’s one of our favourite performers and who is it tonight?” Holmes said before Suri enthusiastically yelled: “Taylor Swift!”
Before going on stage, Suri was so excited she clapped, an onlooker tells PEOPLE.
The actress, 38, dressed casually chic in a long-sleeve ruffled white top with black pants and color coordinated heels while her only child wore a star-patterned dress with a big red bow in her hair.
Holmes and Swift, 27, previously crossed paths working on the 2014 film The Giver.
Backstage, the pair were also spotted mingling with artists and celebrities with Holmes taking a photo with host Elvis Duran.
Other A-listers in attendance included Broadway star Ben Platt and Lindsay Lohan.
Swift performed her hits “Shake It Off,” “…Ready for It?,” “I Don’t Want to Live Forever” and “Look What You Made Me Do” during her set. Similar to her Los Angeles show, the reputation hitmaker brought out Ed Sheeran to perform their duet “End Game.”
This week, Holmes has been in the Big Apple attending a handful of events, including the opening of the Privé Revaux store, which was launched by her long-rumoured partner Jamie Foxx.
In addition, the star attended the 20th-anniversary Screening of Wag The Dog, wearing a black strapless Zac Posen dress.
