Just found this and thought I would share. I warn you. The second one is so hot, it might set your computer on fire...
The first one is well known. It is a video by "Make the Girl Dance" (that is the name of the group). The song is "Baby baby Baby". There is a 480p available:
The second one, I'm not too sure of the artist and song title. It is sort of a knock off of the first one. I believe the artist is "NikitA" and the song is "Verevki". I might be mistaken but it doesn't make one bit of difference as it is so unbelievably HOT!!! There is a 720p (HD) available:
I strongly suggest you put a fire extinguisher close to your screen... You've been warned!
Note: Those two videos are on Youtube and will probably get flagged by the community, so don't wait too long...
