#LOLAlert: We Can’t Get Over These Celebs Impersonating Other Celebs!

From R5 to Alessia Cara, watch these vids & have a laugh!

…

1. R5 impersonated each other! Now, every time we hear “Cali Girls” we think of this vid and smile!

2. Kate McKinnon’s impressions of Justin Bieber and Ellen are legendary. When Kate appeared AS Ellen ON Ellen, it was iconic (and meta)!

3. Ariana Grande is the queen of impressions. Did you catch her on Jimmy Fallon?

4. When Demi appeared on the show, she killed it as Fetty Wap:

5. But this throwback vid of her impersonating Nick and Joe Jonas back in the day is GOLD:

6. We knew Alessia Cara as the most incredible singer and songwriter. But who knew she could do killer impressions of Ariana Grande, Katy Perry, and even Miranda Sings?!
