The actors both debuted new hairdos via social media on Sunday.
Moore, who's character Rebecca is a brunette, is back to a lighter, caramel hue which is closer to her natural dirty blonde locks. Posting the photo on Instagram with her hair stylist by her side, she wrote, "And yes, I wasted no time changing up my hair as sooooon as wrapped up the season on #thisisus."
The same goes for Ventimiglia.
We're used to seeing his character Jack with his signature mustache. That's gone now and his new clean-shaven appearance was documented by Moore's stylist. "Keepin’ it in the Fam #ThisIsUs end of season chop for @miloanthonyventimiglia ❤," she wrote.
"This Is Us" returns Tuesday with the highly anticipated episode of Rebecca and Jack's anniversary. Fans have been dying the past two weeks wondering what will happen next in the emotional rollercoaster series, especially after those pics of that EPIC SPOILER were snapped!
