At the 'Idol' Top 13 Party! Judge Jennifer Lopez Explains Recent Tears

"Extra's" Renee Bargh was at the "American Idol" Top 13 party, getting reactions from judges Steven Tyler, Randy Jackson and Jennifer Lopez.

Lopez was emotional throughout the show, telling Renee, "It's hard, as we were having them sing one by one, I kept looking at the other ones, and I was like, 'God they're so good!'"

The singer also talked about why she teared up recently on an episode of "Q'Viva!" "I had lost my grandmother, my aunt and my uncle all in one year, and so Christmases are kind of funny now. The performer was playing an instrument that was very Puerto Rican, and when he was playing it just reminded me of Christmas and it made me think of family. "

Watch the interviews, including joking with judges Tyler and Jackson and host Ryan Seacrest.
