Lost a Moi... Lolita video

[babyblue558]

Well basically I was watching a ML compilation on YouTube and I spotted a performance I didn't recognise at all. I've been trying to find it for a while now with no luck, so here goes:

The date was 08/26/03 and it looks a little like this...


She's in the ACC dress and it looks like she's duetting with someone I don't recognise... like she did on Star Academy in 2007??



Thanks for the help (and sorry if it's a really obvious one that I've somehow managed to miss completely )
