Mandy Moore reveals how she prepares for the emotional scenes in 'This Is Us'

Mandy Moore has officially won over America's hearts as Rebecca Pearson in "This Is Us"

The 34-year-old actress stepped out last night in New York City at Tao Downtown to celebrate her new DuJour magazine cover. Moore stunned in a ruffled neoprene LWD, completed with sky-high black stilettos and sleek swept over hair.

While Moore is making her press rounds, fans are gearing up for an epic return of season 3. Between the death of Jack Pearson and an emotional ride of relationships, AOL spoke to Mandy about how she prepares to play such a sentient character.

"It sort of differs episode by episode and scenario by scenario, but normally it’s all about courting myself off, being quiet, reflective, listening to some music. Just like reading the scene over and over again; Anything I can do to just be still and be by myself."

While it's no secret that "This Is Us" has arguably become one of the world's most emotional and relatable shows, Mandy admits there's still time for fun on set. And the laughs from her funny co-stars aren't necessarily great for her on-screen prosthetics.

"Sterling is really funny and Justin is hilarious and Chris Sullivan. When I have to do a scene with all three of those guys, it’s not good for anybody because I can’t laugh in my prosthetics. So it’s never a good idea," the Emmy-winner shared with AOL.

"This Is Us" premieres returns tonight, Sept. 25 at 9 p.m on NBC.
