Khloe Kardashian live tweeted her reaction to Scott Disick's emotional breakdown during the January 3 episode of Keeping Up with the Kardashians.

On Sunday night, as Disick cried to Khloe, Kim KardashianKris Jenner and Kourtney Kardashian -- whom he dated for nine years -- about his addictions and loneliness, Khloe got candid on Twitter to defend her sister.

"I've never apologized to all of you for letting all of you down and embarrassing you guys," Disick said to the group during the broadcast, acknowledging his substance abuse issues.

"I know I need to help myself way before I can help [Kourtney] or my kids or whatever, but it's just been a really hard time going from having all of you guys to having nobody. You guys really did so much for me and for so many years that it kills me to the point where I feel like I can't make it up. I've never been as unhappy in my life, you know? If I didn't have those kids, I would kill myself. But I have them and I'm going to be here and I'm going to make it right for them."

Disick has three children with Kourtney -- Mason, 6, Penelope, 3, and Reign, 12 months. The couple split over Fourth of July weekend after the self-proclaimed "Lord" was photographed getting touchy-feely with his ex-girlfriend Chloe Bartoli in Monte Carlo.

As the episode aired on both the east and west coasts, Khloe offered up her thoughts on social media.

"I was literally speechless when Scott walked in #KUWTK. I hate people who play victim. Take accountability people. Own your actions #KUWTK," Khloe tweeted Sunday night. "My stare down is meeeeaaaaannnnn."

Khloe responded to Disick in the episode by suggesting he had no one to blame but himself, which prompted the reality TV star to say on Twitter, "Why am I the only one talking?! Lol I'm just noticing that no one said anything but me. Ha! I guess when you date 1 of us you date all of us."

While some might argue Khloe was too hard on Disick, she tweeted, "Sometimes I'm way too direct but I am all about protecting the ones I love. My intentions are good."

Although Kourtney, 36, and Disick, 32, have been getting along recently and co-parenting quite nicely, Kourtney spent New Year's Eve alone with her kids. She posted a photo of herself kissing Reign on January 1 as Disick promoted a party at 1OAK nightclub in Las Vegas.
