Mollie King, Una Healy, Rochelle Humes, Vanessa White and Frankie Sandford put on an energetic performance at the XL nightclub in New York City.
Dressed in matching black outfits with embellished tops, the fivesome wowed the audience with a routine featuring some of their big hits - and it seems like all the girls were thrilled by the audience reception!
Frankie tweeted: "Such an awesome show tonight in New York! Can't believe we're actually here and people are singing our songs! Thanks guys."
Mollie added: "XL NYC you were incredible tonight! Thank you so much to each and every one of you for making our first show in New York so unforgettable!"
New mum Una also tweeted her thoughts after the gig, saying: "Met so many US Sats fans tonight so exciting!! Thanks so much to everyone at XL in NYC tonight for making our NY debut so sweet!! "
The Saturdays jetted into the US last month to film a new reality show which will see them attempting to break America, and have been spotted hanging out at various star-studded US events.
They were snapped looking gorgeous on the red carpet at the MTV Video Music Awards earlier this month, before attending Perez Hilton's One Night in Los Angeles party, and bagging front row seats at New York Fashion Week.
