One of the guys from The Wanted has Lindsay Lohan's back ... unfortunately for her, it's not the guy she's been trying to bang.
We broke the story ... Lindsay has been gunning to nail Max -- the one with the shaved head -- for the past couple of days ... and partied with the guy at Avenue nightclub the night she was arrested.
But last night, one of Max's fellow boy-banders -- Jay -- let everyone know the guys are still supporting their most infamous fan by wearing a shirt on stage at their concert that read, "Free Lindsay."
As we previously reported, Max rejected Lohan on the night of the fight because she was too sloppy drunk ... and went home with another chick instead.
Lindsay Lohan punched another woman in the face over Max from the boy band "The Wanted" last night ... and we've learned Max was turned off by the fact LiLo was sloppy drunk inside the club ... this according to sources at the club.
We're told ... Lindsay went to the Justin Bieber concert -- but not to see the Biebs -- "The Wanted" was the opening act ... and Lindsay has been scoping Max out for the last few days.
She's not the only one either -- on his way out of his NYC hotel yesterday, Max was swarmed by adoring female fans ... and he even kissed a few.
Sources say Lindsay tried to get backstage after the concert to see him -- but she was blocked. Fast forward to later that evening when Lindsay met up with Max, Jay and Tom at a hotel bar.
The four of them -- along with one of LiLo's friends -- then went to the club Avenue together.
As the evening wore on, we're told Lindsay got drunker and drunker ... and it turned Max off. He then started talking to another woman, which enraged Lindsay. That woman is the one Lindsay is accused of battering. (FYI -- Max was also really drunk).
Ironically, Max washed his hands of both of them -- found another girl in the club -- and went home with her instead ... while Lindsay ended up in jail.
Two days after calling "Voice" judge Christina Aguilera "a bitch" on the radio in New York, one of the guys from The Wanted seemingly apologized in one breath ... and then took another shot at her in the next.
After a guest appearance on the show, the band went on 92.3 NOW in NYC and said, "She's a total bitch. She might not be a bitch in real life, but to us she was a bitch."
Talking outside the Mondrian Hotel today in Hollywood, the one who calls himself Tom was asked about his Xtina comments ... and in back-to-back sentences he said, "We shouldn't have said it, to be honest with you. We just think manners cost nothing, you know what I mean?"
Neither does humility.
One of the singers from "The Wanted" has finally settled the debate -- STRONGLY insinuating the band's hit song "Glad You Came" is really about having an orgasm ... not hanging out with some chick you like.
The video (shot recently in New York) shows "Wanted" singer Tom Parker (left) singing the song on the street with two fans.
Everything's going fine at first -- maybe a little pitchy -- but on the last verse, Tom changes the lyrics, singing instead, "I'm glad you GUSHED" ... and gestures near his crotch.
The debate's been raging for months -- so we gotta ask ...
Things are all good between The Wanted and the boys from One Direction -- in fact, Nathan from The Wanted says he was even trading text messages with Liam from One Direction earlier in the day.
As TMZ first reported, the two boy bands had a run-in earlier this month when they were both booked in the same rehearsal space on the same day. We're told the boys from One Direction cut their rehearsal short because they didn't want to have a confrontation with The Wanted.
But last night in Hollywood, Nathan told us there is no reason for One Direction to be afraid of them. He told us, "I am pretty sure we don't intimate other teenage boys."
Watch til the end of the video if you want to hear a discussion about the going rate of used underwear.
The boy band One Direction was so concerned the other big boy band, The Wanted, was gonna beat on them, they tried to flee a Burbank studio ... but then The Wanted boys showed up.
Here's what we know ... On April 4, One Direction was rehearsing for SNL at CenterStaging, a Burbank rehearsal studio. Sources connected with CenterStaging tell us ... security for the band became aware that The Wanted was about to show up to rehearse for their "American Idol" performance the next day.
We're told the boys from One Direction -- all of them except Liam -- were scared because the British tabloids have been writing about tension and smack talk between the 2 bands. The One Direction lads talked about the guys from The Wanted being tough guys (which apparently is true) and they were worried about getting taunted and manhandled.
Our sources say One Direction decided to abruptly end the session and leave, but before that happened The Wanted showed up. The security team for The Wanted spoke with security for One Direction and discussed One Direction's fears. Security for The Wanted then told band members about One Direction's fears, and Max (from The Wanted) bolted into the studio where One Direction was wrapping up, laughed and gave Liam (he's from One Direction) a hug.
We're told everyone got a laugh out of it -- except Louis from One Direction, who wouldn't go near the boys from The Wanted.
We love boy bands.
In this new boy band era, The Wanted (top) -- Tom Parker, 23, Nathan Sykes, 18, Max George, 23, Siva Kaneswaran, 23, and Jay McGuiness, 21 -- and One Direction (bottom) -- Louis Tomlinson, 20, Niall Horan, 18, Liam Payne, 18, Zayn Malik, 19, and Harry Styles, 19 -- are vying for your crazed screaming tween's dollars.
Question is ...
Breakout British boy band The Wanted has violated the ONE rule of alcohol-fueled karaoke night -- YOU CAN'T ACTUALLY BE GOOD AT SINGING ... and TMZ has the video proof.
It all went down at Rock & Reilly's Monday night in Hollywood ... the boy band -- known for their new hit "Glad You Came" -- grabbed the karaoke mic and belted out the 90s classic song "Iris" by the Goo Goo Dolls ... and damnit ... it was way too good.
Why they weren't immediately kicked out afterwards, we have no idea.
