Linds first got tongues wagging when she partied with the British boy bander at NYC club Avenue and ended up getting arrested, and now it looks like she's followed him across the pond.
Lilo shared this picture of her and Max together in London via her Instagram account, but it seems Max is downplaying their relationship.
"Rumours... That's all... Like I said... 1 million % :) X," he Tweeted shortly after Lindsay posted her pic of them.
Max also went on the record saying LL is more of a party partner.
"She's good to party with but there's definitely not going to be any babies on the horizon," he told E! News recently.
The Wanted are pretty big partiers themselves!
