Justin Beiber's Calvin Klein ads came out recently and Saturday Night Live has perfectly mocked them.

Kate McKinnon is one of the more talented members of the new cast and she does a great job as Beiber. The clip opens with Beiber (McKinnon) on drums before fading to her claiming to "be a big boy now". And just when you think the bit can't get any funnier, it does.

Saturday Night Live is currently in the midst of their 40th anniversary season and kicked off back in September with Chris Pratt as host.

Darrell Hammond has taken over for longtime show announcer Don Pardo who passed away in August.
