This year, Vanessa Hudgens joined Ludacris as co-host of the Billboard Music Awards and the veteran host put her to the test—live, in front of an audience of millions.
When Vanessa admitted that show-opener Nicki Minaj is her rapping hero, Ludacris asked for her best Nicki. And Vanessa delivered, doing a spot-on impression of Nicki's "Monster" verse.
Then, Ludacris put Vanessa to the test again, daring her to belt out some Celine Dion (the powerhouse singer is on-hand to perform "My Heart Will Go On" in honor of Titanic's 20th anniversary). Again, Vanessa nailed it.
Seriously, this clip will go down as a Billboard Music Awards classic:
