Swiss soul singer Stefanie Heinzmann dropped by EA to spend some quality time with the staff along with getting a chance to play The Sims 3.  I cannot really provide much more information than that, but if you understand German, you can visit both SimTimes and Cynamite for the scoop.  I did find 21 photos from the time she spent with them that were Sims related (many others were taken).
