Blush, a five-member multinational girl group, appeared in Seoul Wednesday, showcasing their fifth album.

The group sang its big hits such as “Dance on,” “Holding to a Dream,” “Electric” and “All Star” at a private hall near Dosan Park, southern Seoul.

They also invited Yoon Do-hyun as a special guest. He was a judge and mentor of Project Lotus, a TV audition in 2010 to select members of the newly forming group, Blush. Today’s show exclusively aired live all over the world by the world's No.1 live video streaming website, Ustream (http://www.ustream.tv/channel/hot-issue).

"When I first met them on TV shows, I was worried sick about how they would turn out. But now I am glad to see them do so. They have become professional," said Yoon, who sang his song, “I am a butterfly,” on the stage while playing acoustic guitar.

With one each from the Philippines, India, Hong Kong, Japan and Korea, Blush debuted in 2011 with “Undivided” featuring Snoop Dogg. Their second single “Dance on” placed top of the Billboard Dance Chart.

They are known as the “Asian Spice Girls” due to their powerful dance moves and record producer Eliot Kennedy, who is famous for working with artists such as Celine Dion, Spice Girls, Robbie Williams and Gary Barlow.

Blush, who began promoting their new album in May, performed in Seoul as their final leg of the world tour, including the United States, Hong Kong, Japan and China

The group is expected to appear on domestic TV shows such as SBS MTV’s 'The Show' to make them familiar with Korean fans.
