Voice of the Stars - Shirley Yeung

Is anybody here watching "Voice of the Stars"?  I've watched around four episodes but don't care too much to continue haha.  Anyways, back to the point.  Shirley Yeung appeared in episode 8 and guess who was there to accompany her?  Linda Chung!  From what I know, they've been friends since 'The Bitter Bitten' right?  It was so sweet to see them holding hands hehe.
