Simon and Cheryl, who were on the X Factor judging panel when Harry and Liam were on the show, are great "because they fight", according to the One Direction singers.
Harry and Liam say Cheryl and Simon are good together "because they fight"
"She [Cheryl] is not afraid of him [Simon] at all," Liam told the Mirror. "Obviously some people are too scared to say what they think around him on the show and she’s, like, 'No you've brought me in to do a job and I'm going to do it.'"
The boys also admitted that they can't wait to meet Simon's son Eric.
"I hope we get to meet him soon!" Liam said. "When he’s old enough we can have a kickabout with him."
