The following day, Louis opened up about One Direction‘s fans welcoming Steve into the family.
“The One Direction fans have said that they’ve adopted [Steve] now,” Louis explained to Music Choice.
Steve added, “They’ve adopted me. I’m part of the family. They’re incredible, just the 1D fans, the Louis Tomlinson fans. They’re the definition of what a fan is.”
