The One Direction star posted message to the social networking site on Thursday (16 July) thanking fans for their support in Washington on the latest stop on the 1D world tour.
He said: "Amazing show! Thank you for the support!!"
Perhaps not the tweet fans were hoping for either confirming or denying the baby news that has swept the world since it was announced on Wednesday morning.
Plenty of fans responded to Louis begging him to make a statement:

Louis' said to be expecting a child with US stylist Briana Jungwirth. It's believed they dated in May this year after Louis' split from girlfriend of four years Eleanor Calder.
While Louis and Briana aren't together now, it's said they are close friends and will raise the baby together. Louis, 23, is thought to have been at all Briana's scans so far.
