The entertainment world received some exciting news this weekend as Beyonce welcomed her first child, Blue Ivy Carter. We caught up with fellow music icon Jennifer Lopez, who just heard the happy announcement, and the mother of two lavished her praise on the new mom. 'The best part of [Beyonce's] life is about to begin,' said Lopez fondly. 'I just wish her the best. I know she's going to love it and be a great mom.'
