Louis Walsh has a bit of a reputation for being erratic on X Factor, and tonight was no exception.

The groups headed off to Judges’ Houses with him in Ibiza, and guest judges Fleur East and Alesha Dixon also came along to help out.

Louis was joined by Fleur East and Alesha Dixon (Thames/Syco Entertainment)

But despite Fleur and Alesha pointing out exactly what the audience was thinking when it came to each act, Louis – as usual – decided to go his own way with some very…leftfield decisions.

Viewers couldn’t hide their shock as he let girl groups Skarl3t and 4 of Diamonds go, as well as wildcard Yes Lad and duo Tom and Laura.

Nah what is wrong with Louis!!!!!! 😳😶 #XFactor

Axing 4 of Diamonds was a particularly unpopular choice, especially as all three judges – Louis included – had so many positive things to say about them.

Sad for 4 of Diamonds. They were great! #JudgesHouses #XFactor

In fact, some felt like being a girl group was an automatic disadvantage.

WHY DOES LOUIS HATE GIRL GROUPS #XFactor

So who did get through? Well, 5AM were sort of a popular pick.

That 5am or whatever on X factor will be in the final or win it

And people felt emotional about returning Irish twins The Brooks.

The brooks oh god I'm crying bless them😭 #XFactor

But people absolutely could not believe that undercooked-chicken-row duo Bradley and Ottavio got through.

This is why Louis should never have come back. The joke judge gets the joke act. Decent singers losing out for 'entertainment' #XFactor 🖕🏼
