Question about Arashi's song

[moon-kaka.livejournal.com]

Domo minna, my 1st post here & I'm not sure it's ok to ask or not @_@ It's a small rap part in this video, I don't know from which song. If you know, please help me.
It was in the Hey!Say!Jump's debut concert DVD.

Around 3:57 in this video they started to rap. It was Love so sweet before but I searched in the lyric, there was no rap part like this *sigh*

Thank you so much ^^~
