Has HyunA hinted at a reunion with her Trouble Maker partner Hyunseung?

The 4Minute singer and B2ST idol were spotted together at the CUBE studios recently and HyunA teased fans with a few pictures perhaps suggesting the two are ready for a comeback.

HyunA posted a handful of pictures of herself at work in the studio at her agency, CUBE Entertainment - one of which features a label-mate Hyunseung.

In the image, the pair are posing should to shoulder in front of the CUBE Entertainment logo while covering their faces. But Trouble Maker fans are not so easily fooled and realized the person looking so shy next to HyunA was none other than B2ST's Hyunseung.

Now the internet is abuzz with rumors of the duo's comeback.

It has been nearly two years since the mixed group sub-unit debuted with the hit single "Trouble Maker," a song quite a bit different from their work with their respective groups.

"Trouble Maker" won the pair several awards including the Mnet Asian Music Award for Best Collaboration Performance and the Golden Disk Award for Best Dance Performance.
