All four members of 2NE1 reunited for the first time in a while to celebrate the release of Park Bom's new single 'Flower.'

On March 15, Park Bom posted a short video with the caption '2NE1' and a few emoticons. In the video that was posted, Park Bom starts off by showing herself then turns the camera to show the rest of the members.

It revealed that the four members were spending time together and having a meal together in a private room at a restaurant. The members looked to the camera, and all shouted "Hello," greeting the fans.

After that, CL continues to say, "Are we just going to say 'Hello'? Congratulations on your song. I recommend this new song." Park Bom then asked, "What is the name of my new song?" to which Dara raised her hand and exclaimed, "It's 'Flower.' Give me a prize."

Just last week, CL, Dara, and Minzy were seen hanging out as they posted a photo on each of their Instagram. Although Park Bom was not with them, she was still tagged on the photo as the members still shared a close friendship.

Now all four of them have gathered to celebrate Park Bom's comeback. Meanwhile, 2NE1 debuted back in 2009 and caused a sensation with their hit songs "Fire," "I Don't Care," and more.
