MBLAQ's Lee Joon and Seung Ho have posted mysterious teasers for an upcoming secret project!

The two artists are holding up a sketchbook with enigmatic drawings on them. Lee Joon's simply says "Sexy!" while Seung Ho's... well... we're not quite sure!

Could this tie into the 'Monster' teaser image that J.Tune released a few days ago? Only time will tell!
