"Maybe it's about time you realise it's not all about you and shut the f-k up for once, let them speak".
Heated stuff! Unless Liam is particularly passionate about polite celebrity-media relations, his upset is most likely to have been caused by the fact that Louis was less than complimentary about his girlfriend - who Louis has continuously thrown shade towards over the years.
The clash between Louis and Liam isn't the first time the pair have butted heads.
The feud between Louis, 64, and Cheryl, 33, seems far from dead, as during an X Factor live show last month, Simon joked about his axed act Sam Lavery's song I'll Stand By You, saying at the time: 'I'm dedicating this one to Louis, it's a Girls Aloud song'.
Payne took issue with Walsh's response to the question, 'What would you do if Simon invites Cheryl back?' According to The Mirror, he replied: 'Well Simon wouldn't invite Cheryl back because we have Nicole. "We have Nicole and Sharon, we don't need another girl", he told a reporter.
He continued: "So go and f**k off now".
And while they've only been dating for just under a year, Liam is reportedly thinking about popping the question in the delivery room, after being inspired by the way Cheryl's BFF Kimberley Walsh's partner Justin Scott proposed two years ago. "It's not about Cheryl, stupid man".
Cheryl quit X Factor earlier this year.
She showed off her rounded stomach in a clingy jersey dress and open coat while attending a Christmas charity carol concert with Liam in London, which benefited her Cheryl's Trust foundation.
He said: "It's not about The Spice Girls, it's about Five After Midnight.so stop talking about them".
"They're lucky f**kers, but some get a sense of entitlement and believe the hype". One Direction fans may not vote for them now even more due to their mentor.
