Two young daughters sitting in the backseat of their parents' car both have appropriately adorable, yet completely opposite reactions to the very big news that they're being surprised with a trip to Disneyland.

We first met Lily, 8, as she reached viral video super stardom two years ago when her reaction to being surprised with her first trip to Disneyland exploded online. She cried, she was in shock, and America fell in love.

Now, two years later, it's her younger sister Chloe's turn to steal the viral video spotlight.

Independent 2-Year-Old Tells Daddy, 'Worry About Yourself'

As the whole family was driving to school the morning of Sept. 12, Katie Clem, the girls' mother, got her husband to pull the car over to break the news they were actually skipping school that day, and instead were going on another trip to Disneyland.

"Lily's birthday was coming up," Clem, 33, of the Salt Lake City area, told GoodMorningAmerica.com. "She wanted to go to Disneyland during Halloween time. And with Chloe being older, I wanted her to be involved too."

As to be expected, Lily has the exact same emotional reaction she did before: overwhelmed, crying, grateful to hear the news.

However, as 2-year-old Chloe is sitting next to her, she is caught on camera with a completely unamused look on her face, hilariously unfazed by her sister's shenanigans.

Chloe's oh-so-apparent "I'm so over this" expression has already garnered more than 251,000 views on YouTube.

"That is so funny to me, because that's what Chloe does, a little stink face," said Clem. "She's staring at Lily like, 'What is your problem?' It wasn't a big deal to me at the time, but to see the reaction of people liking Chloe's response is pretty funny."

Clem acknowledges how different her two daughters behave, and that's what keeps her on her toes.

"Lily has always been like that since she was Chloe's age. She's very emotional, wears her heart on her sleeve," said Clem. "But Chloe is my little danger kid. She's just like, 'Yeah, whatever.' I don't even have any words for it."

Both girls are oblivious to their internet fame, but it's safe to say Chloe's new fan base hopes her sassy attitude is here to stay.
