On Rayver's cover of John Mayer, Julie Anne comments 'kakaproud, husay'

Ah Julie Anne San Jose and Rayver Cruz.

Who knows what exactly is going on between them but we are enjoying their banter on Instagram.

Like what happened on Wednesday: Rayver uploaded a video of himself doing a cover of "My Stupid Mouth" by John Mayer from inside his room. 

Julie Anne gave her approval, commenting how she felt proud of him and that his bedroom serenade was pretty good.

"Syempre ikaw teach ko eh," Rayver replied to Julie.

Like most of their banter, it went on with Julie asking Rayver to "teach me when you get back" and Rayver replying again with an invitation to do a duet cover.

"Sige wait kita," was Julie Anne's amicable reply.

Fans have been noticing #JulieVer's chemistry for a long time now, with the two upping the kilig factor at Julie Anne's recently concluded "Limitless Live" concert, where Rayver performed.

The pair has since been doing duet covers on Instagram, which have become something of a source of kilig for their fans and followers. — LA, GMA News
