Congratulations to Mandy!
She was spotted a couple days ago with a diamond on that finger:
Mandy herself hasn't confirmed the news, but her This Is Us co-stars spilled the beans to Entertainment Tonight!
"I was just in the studio with her boyfriend, well now fiancé, Taylor. He didn't say a word! He seemed a little effervescent, but he's always pretty effervescent... I know him very well,.He's quickly becoming one of my favorite people, and he and Mandy are an incredible couple."
"I think it's amazing. Good for her. I'm happy for her. Taylor is an amazing guy. I love him so much. I love Mandy so much. I'm really happy that they're going to be joining the club."
"I've seen the sparkler, but I have not heard the story yet because I have not seen her yet. [Moore] just sent out an alert over our family text chain, so I can't wait to hear about it."
