The band was in the middle of performing "No Way" when Jauregui first broke down during her solo portion of the song. Fans cheered for the singer, but it was bandmate Normani Kordei who reached out to comfort Jauregui, who stood back up moments later to finish the song.
According to fans at the concert, Jauregui also started crying while performing "Scared of Happy."
Fans immediately tweeted messages of support to the 20-year-old singer, who took to Twitter the next day to assure Harmonizers that she was okay.
"Thankyou Texas for your amazing shows and thank you so much PHOENIX your energy was insane last night," she tweeted on Friday.
