Though Iggy's rapping was less-than-stellar due to some pretty awkward timing, it was undoubtedly Danish singer Mø's nervous dancing and offbeat singing that received the worst of the criticism.
Mø, 26, acknowledged her not-so-great SNL debut on Twitter Sunday, posting a handwritten note.
"So ... Yesterday, as some of u might know, I performed alongside @IggyAzalea at @SaturdayNightLive," she wrote. "I was BEYOND excited (!!!) - but unfortunately I had some technical issues which caused latency on my vocals, and as a result I got confused and my timing was off. It pains me and I'm SO sad today. But life goes on ... "
But though Mø might be the one apologizing Sunday, the performance is sure to bring out all the Iggy Azalea haters in full-force, who point out that this isn't the first time a performance by the 24-year-old rapper has gone awry.
Iggy apologized in May for herDancing with the Stars flub
in which she had to halt "Fancy" midway because of a faulty earpiece, and in September, video of her performing "Acting Like That" with Jennifer Lopez at Chicago's B96 Summerbash had people calling her out for not even attempting to lip-synch.
And who could forget her epic stage fall at a MTV VMA benefit show in August?
No apology yet from Iggy for this most recent disappointment -- or who's to blame.
