Harry went on his first date with Millie a couple weeks ago, after meeting at the BRIT Awards, and they totally hit it off.
They made plans for a second date this past weekend. Millie was reportedly really looking forward to it and even traveled two hours from London to Cardiff to meet Harry at a club.
But, the One Direction star didn't show up!
A source says: "It was nothing personal — he just wants to keep things casual with Millie at the moment."
Well, that's fine, but might he have given Millie a heads-up?
The source adds: “It’s not going to work out between them any time soon.”
