So, a fan in the audience says how she performed "Underneath the Tree" twice and stopped halfway through the performance the first time. As she said yesterday on the Today show she is still experiencing morning sickness. The fan in attendance thinks she switched to performing "Don't Rush" (a song off of her greatest hits album...released last year) because it's an easier vocal as it doesn't have any crazy high notes. BUT according to someone at NBC they said she performed "Underneath the Tree" twice for the Christmas special (airing December 11th at 10pm on NBC) and that doesn't make a lot of sense because I was at the Christmas taping and she performed "Underneath the Tree" twice. 1 taping was said to have been used for the Christmas special and the 2nd take they said was gonna be used for the music video. Either way, home girl needs to take a break. She's not out of her first trimester yet and yeah, she needs to chillax.
