"Happy 40th birthday to the one and only Mandy Moore! You turned the big 4-0 on April 10th and we can't believe it! It feels like just yesterday you were singing about candy and being only 15. But now, you rock it on This Is Us and have us all thinking about Jack and Rebecca's love story. We hope you celebrate this milestone birthday in true Mandy Moore fashion - surrounded by love, laughter, and plenty of chocolate cake. Here's to another 40 years of fabulousness!"
