See SNL promo: Jim Carrey tries to drop "mad rhymes" with Iggy Azalea

Jim Carrey and Iggy Azalea have starred in new promos for Saturday Night Live's Halloween show.

Carrey attempts to show off his hip-hop credentials by "dropping mad rhymes" for Azalea in a mini-sketch, but is foiled by his own mouth.

The duo also preview all of the spooky hijinks that viewers can expect in honour of Halloween.

Carrey will be hosting for the third time this weekend, having last appeared on the sketch comedy series back in January 2011.

He is promoting the highly-anticipated comedy sequel Dumb and Dumber To.

Azalea is expected to be joined by Mø for a performance of their new track 'Beg for It'.

Writer Leslie Jones will be making her first official appearance as an SNL cast member as well.

Saturday Night Live airs at 11.30pm ET on NBC. Listen to 'Beg for It' below:
