The 25-year-old Florence and the Machine singer landed back here after months on tour in Australia and the US, reported Sun online.
"I think we've been on tour for about three years and it's pretty much what we do now. It does get to the stage where you just cry all the time," Welch said.
"For the rest of this year, it's tour, tour, tour, tour, tour, tour, tour. Stop. And then I don't know... Get committed or something," she added.
Welch shared her delight at being home, on Twitter, saying, "London, I love you, Thanks for having me back, am going to sleep in you now for hundreds and hundreds of hours."
