Your secret's safe with us, Hazza. Why keep your country tune lovin' ways on the hush-hush though? Or maybe he's just putting a disclaimer out there so that people don't start gossiping that he and Kacey are dating.
Kacey seemed a bit confused by Harry's tweet as well, responding "Thank you?," as if wondering if his request not to tell anyone was kind of strange.
Meanwhile, Kacey's taken a little stroll over into Harry's territory recently – pop music - as she hit the road with Katy Perry. She told Billboard.com: "It's going to be really interesting and really good for me, I believe, 'cause there are a lot of people who would probably never have heard country music otherwise. So I'm proud to be an ambassador, and if I pick up some new fans along the way, I think that's great. I think with Katy, with her music and style, anything goes, and I think if people are just coming to hear great music and have a great time, it'll make sense."
UPDATE: Harry later tweeted: "Actually, tell everyone." Nice.
