We all witnessed some sad singing from the great Mariah Carey, but she has seen her days of greatness hitting those high notes and there are plenty of videos to prove it! 

Back in 2010 Mariah did a ABC Christmas special and sang alongside her mom Patricia Carey. Her mother was a very talented well known opera singer in her prime and obviously passed those pipes along to Mariah. They sang a rendition of "O Come All Ye Faithful" and they wowed the crowd. Take a listen!

She also sang "Joy to the World" back in 2013 in Rockafeller Plaza for the CHristmas tree lighting and did an amazing job!

Apparently when she was late to the Rockafeller Plaza this year she was 3 hours late and it was due to a meeting with her divorce lawyer. The D word is not a fun thing to handle and sometimes it makes everyday life difficult. Cut the diva some slack, she's still a great singer.
