Amidst the heated competition of boy bands and solo artistes - both old and new - fan girls are now rejoicing at the unexpected influx of testosterone that has been dearly missed in the earlier half of 2009. Among them, Lee Ki Gwang of B2ST BEAST and Lee Joon of MBLAQ are responsible for a great majority of the sudden rise in blood pressure and uncontrollable breathing pattern in females. Both members of each rookie group revealed their "chocolate abs" in the past few days, prompting netizens to draw the two hot bods in comparison. Lee Ki Gwang bares his upper body for the first time in a scene from the MV teaser of BEAST's debut track "Bad Girl." A representative of BEAST claimed, "In the middle of Lee Ki Gwang's busy schedule, he made time to exercise regularly and, hence was able to build chocolate-like abs." On the other hand, Lee Joon flaunts his body in a more playful manner during MBLAQ's debut performance on M! Countdown. Although his upper half is only slightly covered by, what appears to be, a regular t-shirt that has gone through a paper shredder several times, the public got the chance to take a closer look at his defined abs as he lifts his shirt while doing a body roll (bless you, choreographer!) Now that you have had a chance to ogle at the two members, it's time to make your judgment: does Lee Ki Gwang's "chocolate abs" bring out your inner bad girl or does Lee Joon's hot bod just make you want to scream "oh yeah"?
