Also dropping that exact day of all days: Ridiculously popular children's character Peppa Pig's My First Album. They clap back at each other with the most hilarious comments.
The 29-year-old rap star recently released her latest studio album, "In My Defense", but has admitted to doubting she'd be able to compete with the cartoon star's debut release, "My First Album".
Iggy Azalea made an embarrassing faux pas while promoting her new album, revealing she had bought a copy.
Peppa shockingly replied and wrote "Peppa's so fancy, you already know" referencing the riff to Iggy's song "Fancy".
Iggy then fired back and threw shade at Peppa, writing "Collab with me now or you'll end up a breakfast special, Peppa".
Naturally, fans weighed in with their thoughts about this dream collaboration - and Azalea's threat to serve the lovable swine on a plate alongside fried eggs and hash browns. News, Iggy clarified that she was nervous about Peppa Pig releasing an album.
Iggy and Peppa recently engaged in a tongue-in-cheek Twitter beef, with the pair exchanging jokes on the micro-blogging platform. "But I'm beating her on the chart today, surprisingly".
Indeed, Iggy's album hit No. 22 on the iTunes U.K. chart, while Peppa's is at No. 55.
"That was my favorite collaboration I think I've ever done", she said. "I'm beat before I even started".
