A number of eye-raising Katy Perry tweets where she appears to be feuding with fellow singer Sky Ferreira have recently resurfaced.

The I Kissed a Girl hitmaker, 39 — who recently quit American Idol — seemingly took a few digs at the Los Angeles native, 31, back in 2010, with the tweets still visible on her page today.

It’s unclear if the two were actually feuding or simply joking around, as there are photos of them from that time period suggesting they were friends.

In another one Katy wrote ‘Maybe u should stop sleeping with so many DJ’s’ in response to Sky asking, ‘Sorry but how the f**k have some people heard songs off my album?’

Another post saw Sky ask ‘can singers stop giving fans pet names? Please,’ to which Katy replied, ‘You’re just jelly u don’t have any yet.’

Yet another post from 14-years ago directed at Sky read, ‘I have a rope’, though the context is unclear as the original post to which she was replying is no longer available.

At the time of the tweets Katy would have been 25, while Sky was 17.

There are a number photos of the twosome hanging out together after the Tweets were published.

In 2012 they were seen attending the 20th Annual Elton John AIDS Foundation Academy Awards Viewing Party in West Hollywood and both matched in silver gowns as they posed together.

That same year they were also spotted together at the Coachella Music Festival in Indio.

Sky rose to fame after she began uploading videos of herself singing to Myspace as a teenager, which led to a recording contract with Parlophone in 2009.

She released her first EP, As If!, in 2011. It was followed by her second EP Ghost in 2012.

Katy seemingly took a number of digs at Sky back in 2010, with the tweets still visible on her page today, though some believe they were jokes. One Tweet reads: '@fkyferreira is it hard being pregnant @ 17? Hope it doesn't look like a monkey...'

The multihyphenate has been plotting her exit from the show since last year, when it was revealed she felt repeatedly ‘thrown under the bus by producers’ who she believed were purposefully editing her to look like the ‘nasty judge’ insiders exclusively revealed to DailyMail.com
