Music legend Ozzy Osbourne passed away in July at the age of 76.
The singer was survived by his kids and family who mainly reside in US.
Ozzy and his wife Sharon lived in US for decades but wanted to spend their last years in their native land, UK.
Leaving behind their kids and grandkids in US, the couple moved to their mansion in Buckinghamshire.
Speaking in BBC documentary Sharon and Ozzy Osbourne: Coming Home, which filmed before Ozzy’s death, Jack talked about the major move.
“Emotionally ... I think it's gonna be difficult for sure.”, Jack said when his parents were moving.
He also said that he could not spend a lot of time in UK but could bring his kids once a year.
“You learn things from your grandparents, you know, and just having the ability to have a kind of closeness and a rapport with their grandparents is, it's priceless”, he added.
Jack also talked about Sharon’s relationship with his daughter Pearl which he feared would be affected.
The show was set to appear in August but was pushed back because of the singer’s death.
