For someone so sweet and cheerful, it's curious that Mandy Moore is known best for making people cry. Dropping by the The Tonight Show on Monday night (Sept. 24), the This Is Us star chatted with Jimmy Fallon about her past projects and what's coming up while still finding time to play some signature Tonight Show games.

Currently on the third season of NBC's hit tearjerker This Is Us, Moore has a leading role in the series that follows the lives and families of two parents and their three children, all born on their father's birthday. Filmed in two different timelines, Moore is the only person in the cast who performs in both eras of the show -- showcasing her acting skills by playing her younger self and a much older version, thanks to eerie realistic prosthetics. "You're so good at acting different ages of yourself, it's fascinating! You make us feel all the feels," Fallon gushed. "That's our goal!" Moore proudly replied.   

"I'm glad I can laugh and smile in this season though, I've cried all the tears that are humanly possible in the past two seasons," Moore said, noting how light-hearted the show's third season is. "I feel like you always make people have the good cries," Fallon replied, reminding the actress of her first role in the iconic teen drama A Walk to Remember, when Moore was only 16. “I’m slightly flabbergasted that the thing I’m known for my career is making people cry.” Moore admitted.

 

Fallon then invited Moore to play a This Is Us / Walk to Remember quiz, where he would recite a quote from either the show or the movie, and she had to guess which one it was from. "You have to promise, you won't fall in love with me," the host warned. 

The duo then followed up with the latest edition of  "The Singing Whisper Challenge." With Moore wearing the noise-canceling headphones, Fallon started with Justin Bieber's "Sorry." Moore, laughing and very confused, couldn't understand anything Fallon was saying. "I'm the worst lip reader in the world!" she said. 

Switching up roles, Moore read the lyrics of TLC's "No Scrubs" for Fallon, who got the title in under a minute. Moore, ready to redeem herself on the second round, focused and got "I Want It That Way" by the Backstreet Boys just as quickly.
