B1A4 is confirmed to make their grand comeback by the end of this month. It's been nearly a year since the K-Pop group released "Good Timing", so now they are reportedly putting much effort to their fourth Korean studio album.

A source from the group's agency WM Entertainment recently revealed, "B1A4 is aiming to release a new album in late September. They're currently putting a lot of effort into their album, so please look forward to it."

According to South Korean publication OSEN, B1A4's Jinyoung will be producing the group's comeback single once again. The boyband headed to Australia on Wednesday, September 6 to film the music video for the title track. However, the concept for the new album is still kept under wraps.

Earlier this year, the group teased about the comeback project during an interview with Billboard. "We have [new album] plans, but we don't know when it's coming out," Baro said. "We always try to make comebacks--Jinyoung and CNU are always writing songs--we haven't recorded anything yet, but soon. But we'll say please always look forward to it."

Meanwhile, in another interview with Soompi, CNU shared that the group planned to release more music this year. "I think our goal is to release a lot of albums!" he explained. "We did a lot of individual activities last year so we didn't release a lot of albums but this year we want to release more albums for our fans."

B1A4 debuted in April 2011 with single "O.K" off their EP "Let's Fly" after being publicly introduced through webtoon. They have released seven studio albums (three Korean and four Japanese), six EPs and four compilations. In addition to their success in Korean and Japan, the group has toured in the U.S.
