"I hope Julia will accept this public apology," Eric Roberts, 68, now writes, according to People. "It was an asinine thing to have said."

His drug addiction led to a difficult relationship with Julia Roberts, 56, and his half-sister, Nancy Motes, with Eric Roberts writing that it was "dangerous to be around me." But the "biggest consequence" of his drug use was losing custody of his daughter, Emma Roberts. The custody battle led to a rift with Julia Roberts, who sided with Emma Roberts' mother, Kim Cunningham. In his memoir, Eric Roberts admits it was ultimately the right move.

"I imagine I will remain as Julia's brother and Emma Roberts' dad for the rest of my life," he writes, according to the outlet. "I'd like to make good on that, to move aside proudly and with grace. That's part of the reason for writing the book."

Earlier this year, Eric Roberts discussed how he "can't talk about" his sister or daughter in an interview on the "Still Here Hollywood" podcast. When host and entertainment journalist Steve Kmetko asked how his sister was doing, the actor replied, "You'll have to ask her.

"I love my sister, but I can't talk about her," Roberts said on the April 1 episode. "And also, my daughter told me not to talk about her, but I stumble and do. I'm not supposed to talk about either of them, but I do."

Later in the episode, when asked which actors he admires, the Oscar nominee replied, "I'm in love with my daughter's work these days. Like, I can't believe how great she's become. I'm so proud of her I can't see straight."
