The Carter patriarch passed away on Tuesday evening in Florida.
“I am heartbroken to share the news that our father, Robert, passed away last night…” Nick, 37, tweeted on Wednesday. “While we learn more about the cause of death, and begin the grieving process, we ask that our privacy be respected at this difficult time.”
“My heart is completely shattered,” Aaron, 29, tweeted — sharing the last photo the two took together. “I’m in shock and I loved my dad so much. #RIP DADDY I Love You.” In an Instagram post, he added, “My heart is broken. We are so hurt we lost you poppa way too soon. You were never human to me, you were always my real life super hero.”
She, Nick, Aaron, Bob, and her two other siblings — Angel, 29, and Bobbie Jean, 35 — were featured on the family’s 2006 reality show House of Carters.
The Carter family has had a fractious relationship over the years, with Bob and ex-wife Jane Carter divorcing in 2004 and Bob marrying Ginger Elrod that same year.
“We’ve had some very tough times,” Bob told PEOPLE in 2008. “There’s a lot of pitfalls to growing up in the public eye.”
In his 2013 book Facing the Music and Living to Talk About It, Nick explained that while his relationship with his family has been “toxic” in the past, he was working in therapy to become a better communicator.
TMZ was first to report news of Bob’s death.
