CeeLo Green still Happy even though not Singing the song Happy I bet the song "Happy"by Pharrel Williams needs no introduction, well apparently the song was offered to Ceelo but he turned it down, for reasons best known to him, well if you recall even Pharrel himself is stunned by the huge success of the record as he admitted while being interviewd by Oprah thatt he neva saw it coming. One things for sure though cos right now I know Pharrel is happy and I hope Ceelo is too.
