According to the NYPD, British boy band One Direction attracted an estimated 18,000 people to the plaza outside Rockefeller Center temporarily renamed Studio 1D.

Some fans of the group got in line for the touted concert days in advance, one mother-daughter duo actually arrived last Friday to hold their place in line. "We haven’t showered all week. We just wiped off with baby wipes!” she told Matt Lauer, who surprised the superfans with tickets to the "This Is Us" premiere.

In betewen sets, Savannah Guthrie and Lauer interviewed the teen heartthrobs. 

Guthrie, who mixed up Liam Payne with other members of the band several times quipped at one point, "Liam has some news. Who just got engaged?" (Embarrassing, Savannah, you should know your 1D).

A gracious newly-engaged Zayn Malik responded on behalf of him and his fiancee, Perrie Edwards: "We're really happy!" he exclaimed. Before Malik could divulge details on when the nuptials will take place, Niall Horan cut in with, "I'm pregnant!"
