Lady Gaga will be a very busy lady tonight as she appears on two shows on different network. First, the pop queen will appear on So You Think You Can Dance for a second night in a row, this time as a performer rather than as a judge. Later on, she'll pop up on Jimmy Kimmel Live, where she will also perform. When it comes to Gaga, it's hard to know what we're in for, but it's a safe bet that she'll wear very different outfits and play different songs for each show.
