While this is technically off Usher's 2004 LP, 'Confessions,' 'My Boo' is just one of those tracks that would have probably not have had the same charm it had without the help of Alicia Keys. This isn't the first time we've seen the two collaborate. The two did a remixed version of Keys' 'If I Ain't Got You' for the international version of her album, 'The Diary of Alicia Keys.'

Set in the Big Apple, we see Usher and Keys reminisce over their "past relationship." And although time has passed since the coupled up period (at least in this video), the two reunite in the middle of Time Square and have what could possibly be the most adorable version of vocal Olympics we have ever seen.
