Recently, the Wonder Girls guested on MBC's music-talk show program, 'Beautiful Concert', where members Sunye and Ye Eun delivered a solid cover of "When You Believe". The song was originally sung by Mariah Carey and Whitney Houston for the 'Prince of Egypt' OST. Ye Eun and Sunye performed entirely in English, blowing everyone away with their pronunciation and strong vocals. The Wonder Girls also performed their new song, "Be My Baby", so check out both stages below: - Remember to watch the rest of the concert's performances here!
