Ashton Irwin, Calum Hood, Michael Clifford and Luke Hemmings previously were spending a lot of time stateside in Los Angeles to work on their next studio album, but they recently flew home for some downtime prior to their headlining tour kicking off.

The Aussies have now relocated to London where they are probably going to get into rehearsing for their upcoming tour, which kicks off on May 4 in Portugal.

The guys unfortunately were not able to greet fans that were in the airport for their arrival due to safety issues, which has happened in the past, but they always send their apologies to the fans via Twitter.

"[S]orry we couldn't see you geezers at the airport," Clifford shared on Twitter after declaring his presence in "London townnnnnn."

Hemmings expressed similar thoughts, but added, "sorry about the airport, the airport security didn't want us to come out for safety reasons."  

The vocalist and guitarist even joked that he "looked like a zombie" so it was okay that the fans couldn't see him.

In other 5SOS news, it seems as though Irwin brought his rumored girlfriend Bryana Holly with him to London, which a fan update Twitter account shared, photo included of the drummer being affectionate with her.
