The 'Little Things' stars take a moment to look at the Bradford-born member of the group.
One Direction can be seen gushing about their bandmate Zayn Malik in a new exclusive clip from the DVD for their This Is Us movie.
The group's DVD includes new never-before seen documentary footage and the five-piece have been teasing fans with clips for the past weeks.
Liam starts off the talk of his bandmate by saying: "Zayn wears his heart on his sleeve."
"He's got a real big heart, even though he won't admit it," added Louis Tomlinson.
They also go on to reveal how much Zayn hates to get out of bed and the arduous task they all have of trying to wake him up.
One Direction's This Is Us DVD is released on 19th December.
