Curtis, currently in Melbourne to visit family, posted a photo of her first day in the coastal Australian city on Monday.

Within a day, that post got more than 165,000 likes and some 700 comments, including one from the verified Instagram account of BLACKPINK House. It left a queen chess piece emoji, to which Curtis replied with a heart and a surprised emoji.

"BLACKPINK House" is the title of a reality show starring the four members of the YG Entertainment girl group. Its Instagram account, which has more than half a million followers, is apart from the official BLACKPINK page on the image-sharing platform.

On Twitter, Curtis expressed "kilig" and surprise over BLACKPINK's comment. "I'm still not over doon sa nag-comment sa IG ko. Gulat and kilig me! Like how did this happen?" she wrote.

I’m still not over dun sa nagcomment sa IG ko. Gulat and Kilig me!!! 😍 Like how did this happen? 🤷🏻‍♀️ 🖤💗#SoHappy — Anne Curtis-Smith (@annecurtissmith) March 27, 2018

Several of Curtis' fellow K-pop fans who noticed the exchange shared similar speculation: that the comment was likely left by BLACKPINK member Rosé, who like the Kapamilya actress was raised in Australia. That, however, has yet to be confirmed.

Curtis' latest K-pop fan girl moment follows a viral greeting of iKON rapper Bobby for 6-year-old Scarlett Kramer, of the local Team Kramer fame, after she made a tearful plea for the K-pop artist to attend her birthday party.
