Fans are going wild over�B2ST and MBLAQ's group photo from Las Vegas. On November 27th, B2ST's Doojoon tweeted, "M-ST got together and took a photo!" The two idol groups showed off their close friendship in the photo, and even introduced a nickname for themselves, 'M-ST' (MBLAQ + B2ST). Both B2ST and MBLAQ were considered to be rivals since they debuted at the same time. But this photo only goes to show that the rivalry is more public speculation than anything, and that the two groups are good friends. Netizens wrote, "It's nice to see easygoing people together", "Haha. I like M-ST. When is the first album coming out?", "All of you oppas are getting more handsome as time goes by." Source: Star News
