Members of The Wanted find Max George's high-profile affair with Lindsay Lohan "horrifying".
Max and Lindsay have been hanging out quite a bit since the actress went backstage at the British boy band's Jingle Ball concert in Philadelphia last week.
Lindsay was Max's tour bus guest and the couple have been seen making out and partying across several states together.
Max's fellow The Wanted bandmates Siva Kaneswaran, Jay McGuiness, Tom Parker and Nathan Sykes don't want Lindsay around.
"Ever since Max and Lindsay started hooking up several weeks ago, his fellow band members have found the amount of unwanted attention the group has received horrifying," a source told Radar Online.
"They have worked very hard to get where they are, and yes, the boys do party, but Lindsay brings all of her nonsense and drama.
"It's only a matter of time before Max and possibly the band are caught in the crossfire of Lindsay's wild antics. It was only two weeks ago that she allegedly punched someone while trying to hook up with Max. Lindsay is just bad news, and a major distraction to the band. There are plans for The Wanted to open for newly announced Justin Bieber tour dates in 2013, and Lindsay won't be welcome on the road with the band."
