The British girl band posted plenty of photos and videos to Instagram last night (6 August) showing just how excited they were to watch Queen B sing live.
The girls got glammed up and showed off their individual styles as they took their seats in the Barclays Centre in Brooklyn.
Leigh-Anne Pinnock, who returned from a short holiday to Marbella with boyfriend Jordan Kiffin last week, wowed in a fitted monochrome dress with matching pointed heels.
Jade Thirlwall kept it simple in high-waisted jeans, a black t-shirt and aztec-style wedges, while Jesy Nelson rocked a red Adidas American-style jersey top.
Singleton Jesy was definitely in the party spirit as she quoted Beyoncé's famous lyrics. She said: "All the single ladies put your hands up... Ready for Beyonce Jesy x #LittleMixInTheBigApple."
We reckon Jade was the most excited though, as she performed a dance in her seat while waiting for Beyoncé to appear!
Jesy, Jade, Leigh-Anne and bandmate Perrie Edwards jetted over to the States to perform a gig at the Highline Ballroom on Sunday (4 August) in New York.
They were greeted by masses of fans at the airport and it's no surprise, as they've been taking the US by storm in recent months.
In June, the girls celebrated chart success after their album DNA debuted in the US charts at No. 4 - making it the best selling debut album by a British girl group in the States.
