Columbus Short is denying the cheating allegations his wife, Karrine Steffans, is making about him on social media.
The 37-year-old author posted a photo and video to her Instagram on Monday night, showing the former Scandal star solemnly sitting in what appears to be a lobby with clothes strewn about from a suitcase. "Somebody come get @officialcshort cheating a** and all his sh**," she captioned the first post.

In the video, Steffans is heard quietly talking to Short, who does not respond to her. "Nobody has anything to say. Nobody has anything to f**king say," she says off camera. "Oh hey, Columbus. You OK? You feeling OK?"
On Tuesday, Short confirmed to ET that he was splitting from his wife.
"It was too much," the 33-year-old actor said of the incident. "She is a super bright woman, and it's unfortunate some haven't mastered their emotional behaviors."

Short claimed that he has not been unfaithful to Steffans, who he's only been married to for a few months. "I didn't cheat or anything of the sort," he said. "I didn't agree with some things she is putting in her new book, and she basically told me to leave and she was done. So I left."
Short says that's when his wife followed him "downstairs and began filming [him] as she threw [his] clothes everywhere."

"I just want to move on with my life and get back to work," he added. "I don't have time nor do I care for any of this."
Short also took to Twitter to further explain the feud. "Just want to say that it's unfortunate that way things end up. I felt truly that a woman gave me a home and a place to get my mind right," he wrote. "And a place to maturate gifts that I wasn't able to foster, without stability. I love Karrine and her brilliantly talented son. But toxicity of any kind isn't healthy for anyone. I've been working hard to bring you guys quality movies, music and art. And that's exactly what will continue to happen."
"How could you not love a woman who took you in a broken place and allow you to heal," he continued. "I'm thankful for the journey and it ain't the first time I've been homeless. But will definitely be the last!! When it's all said and done stand strong stand tall and most of all UNBROKEN......If I'm still standing you have no excuse! #MoreThanConquerers."

When Short sat down with ET in February, he was still pretty optimistic about his third marriage. "Honestly, it's like the third time's a charm," he said. "I hope it's right. She's awesome and our relationship is like being married to your friend. It's sweet!"
He continued, "When you move on in life and someone can see you for you, that's why we got married. "[It's like,] I'm gonna be with you. I'm cool, I don't care what everybody else thinks. I'm good as long as you love me, we're winning."
The past few years have been tough for the actor. In 2014, after a number of legal incidents and claims of domestic violence leveled against him by his ex-wife, Tanee McCall, Scandal let Short go from the series. Later, he admitted that his struggles with substance abuse and addiction led to his highly publicized run-ins with the law.
