#3: JENNIFER LOPEZ

What to look forward to this year: Let's be honest, J.Lo's 2009 single "Louboutins" was really bad. Lucky for Lopez, Paula Abdul's departure from American Idol opened up a national stage for the Latina singer to reinvent herself. Not only is she releasing her own new music, beginning with her new Pitbull-assisted single "On the Floor," but as a new judge, along with Steven Tyler, whoever she favors has a great shot at winning his or her own record contract. Why? Because people will be too distracted talking and tweeting about "Jenny from the block" to pay attention to the performances.
