Ready for a challenge? Watch the video above and see if you can pinpoint the mystery star in fewer than 30 seconds.
If you need a helping hand, here are some more details on some of the clues:
1. This actress told eTalk that she'd want Anthony Mackie or Justin Timberlake to accompany her to the Academy Awards — before finally settling on JT.
"Justin, if you're not doing anything on that night, maybe you could be my date or something," she joked. "It's fine. No pressure!"
Later, on the Oscars red carpet, she revealed to CNN that the "Suit & Tie" singer sent her flowers.
2. Her 61-year-old mother, Alice Tan Ripley, is a gospel singer who competed on Season 5 of America's Got Talent — auditioning with a rendition of Etta James' "At Last" and making it all the way to the semifinals.
3. She revealed on Watch What Happens Live that Joan Cusack tried to dissuade her from acting: "I was at some industry party, and she says, 'Are you an actress?' And I said, 'Yeah!' And she says, 'Oh, honey, you should really quit the business. It's so image-conscious.'"
We're certainly glad she ignored that advice!
