Despite both the singer and LiLo denying that they were ever romantically involved, Max has since revealed to E! News that they did swap spit - but added that they are not dating.
When asked whether they smooched, Max revealed: "Yes, we did - a little one.
"She's a friend of all of ours and she is a lovely girl. We wish her all the best, wherever she is."
While things may have cooled with the Mean Girls star, Max added that he would like to collaborate with One Direction rival Harry Styles' ex-girlfriend Taylor Swift, stating: "I think she's really good."
Bandmate Jay McGuiness then added: "That would be really cool. Someone mentioned that and we thought, 'Wow, that's a really good idea'. So we could get on that."
