The Brit singer recently admitted on BBC Radio 1 that the Twitter feud she and Banks had several months ago inspired her to write a song.
"There was one person that was particularly nasty to me on Twitter for no apparent reason," Allen dished to radio host Nick Grimshaw yesterday. "And I was struggling with finding my voice—not my singing voice, because I've never found that—but my writing voice."
The "Hard Out Here" singer continued, "And this one person was being particularly horrible to me and I happened to be in a studio session at the time, and it was just brilliant because it ignited this juvenile flame in my belly. So thank you, Ms. Banks."
For those of you who don't remember, over the summer, Banks targeted Allen, calling her a one-hit wonder and writing that her kids were "ugly." Banks also tweeted a very unflattering paparazzi shot of Allen sunbathing topless with the caption, "Ugh, bitch bye."
Allen responded by calling out the fact that Banks has never released an actual studio album of her own, writing, "ive had 2 kids since 212 dropped and i bet my my album still comes out 1st. bitch is scared of the ball. OUT."
You're move (or should we say tweet?), Ms. Banks!
