Ubisoft had a hell of a press conference at this year's E3 in LA, made all the more successful by a surprise appearance by Flo Rida. Flo kicked the conference off by performing "Good Feeling", his song that's featured in Ubisoft's upcoming dance game, Just Dance 4.

Mr. Rida also made an appearance in the game's E3 trailer, along with Harley from Epic Meal Time and a bunch of other internet celebs that are slightly outside our expertise. Check out the trailer and see if you can spot them.

We've got an interview with Flo Rida himself coming to you later this week, as well as a chat with none other than Usher, who was on hand to hype Dance Central 3. Watch out for both interviews as the E3 madness continues, and let us know what you think about Flo Rida's performance and Just Dance 4 in the comment or on Twitter.
