Willie Nelson's latest album features his children, sister

Willie Nelson's latest album, "The Willie Nelson Family," features his sister Bobbie and four of his children, including his son Lukas.

Nelson has long been backed by the Family Band, which features his sister Bobbie on the keys. In recent years, his sons Lukas and Micah have joined the group too. Wilson's daughters Paula and Amy occasionally perform with their father, according to the Austin American-Statesman.

The four children appear on the cover of "The Willie Nelson Family" alongside their father and their aunt. According to the outlet, it's the first time Nelson has gathered the full crew for a studio project, though he's featured some family members on various tracks in the past.
