If your mom was Mariah Carey, you'd probably know every song in her catalog backwards and forwards, right?
Well, according to Mimi herself, she's actually surprised that her 8-year-old twins, Monroe and Moroccan, know any of her songs.
Asked by Billboard if the twins have any favorites among her record-setting string of No. 1 hits, she said, "They love 'Always Be My Baby,' 'All I Want for Christmas Is You,' 'We Belong Together.' They surprise me with the songs that they know.
"They’ve been to a lot of the shows -- you always think they’re on their iPads rather than paying attention, but I guess they’re paying attention!" she added.

"I quiz them on a lot of different people’s songs -- Stevie Wonder, Aretha Franklin, Michael Jackson, Prince -- [and] they’ll get it right," she said proudly.
Carey spoke to Billboard because the publication just named her the Top Female Solo Artist of All Time on its charts.
She's the solo artist with the most No. 1 hits on the Hot 100, and the female artist who's spent the most time at the top spot -- 79 weeks!

To see the success on all the different charts, to hear you say that is mind-blowing," Carey responded when asked how she feels about that accomplishment. "I never, ever dreamt of this when I first started. I just wanted to hear my songs on the radio.
"When I look back on the songs that I’ve written that have become part of people’s lives, that’s what makes me the most proud," she added.
