We know that Maya Rudolph is great at impersonations from her SNL days (her Whitney impersonation is almost as missed as Houston herself), but can she do them rapid-fire? Unsurprisingly, she can. Remember: The key to a good impression isn't voice mimicry, it's capturing the essence of whoever it is your impersonating and capturing essences — in this case those of Nicki Minaj, Rihanna and (best of all) Gwen Stefani — is what Rudolph does best.
