Mandy Moore goes from 33 to 66 right before our eyes!
The This Is Us star shared her epic transformation as she became present-day Rebecca Pearson in a handful of clips posted on her social media on Wednesday.
"You know what's happening," Moore captioned one Instagram story, where she's seen with spots and wrinkles on her face. "Getting older is a lot of work," she wrote in the second clip.

The former "Candy" singer also posted a pic of her chair next to her co-star, Sterling K. Brown's. The This Is Us cast returned to work on July 11 and documented their first day at work on season two via social media.
