"What is really weird is that I have been told by so many people, 'Wendy, you called it,'" she said in the interview, published Tuesday. "Including some people from my family who have said the same."
USA TODAY has reached out to Williams' rep for comment.
The former radio host and embattled Bad Boy Records founder have reportedly not seen eye-to-eye for decades. Charlamagne Tha God, who served as her radio show's co-host in the 2000s, has claimed Williams, 60, has previously had a contentious relationship with Combs, 54, as far back as during her time hosting her gossip and celebrity news show in the 1990s and early 2000s.
Now, she says, justice is finally starting to be served: "It is about time," she told the outlet.
"To see this video on TV of (Cassie) getting pummeled ... it was just horrific," she added, referring to the 2016 hotel surveillance video of Combs assaulting ex-girlfriend Cassie Ventura. "But now you have to think, how many more times? How many people? How many more women? It's just so horrible."
For her own part, Williams said she was "doing good." The host and actress was spotted out and about in August, the first time since her private legal and medical issues became public earlier this year.
Wendy Williams received small sum for 'stomach-turning' Lifetime doc, lawsuit alleges
In September, the former talk show host's guardian, Sabrina Morrissey, filed an amended complaint in New York as part of a lawsuit against A+E Networks over the Lifetime documentary "Where is Wendy Williams?" Morrissey alleged Williams was not capable of consenting to be filmed for the documentary.
Combs, who was arrested on Sept. 16 and arraigned on sex trafficking, racketeering and transportation to engage in prostitution charges the following day, has been incarcerated in the Special Housing Unit at Brooklyn's Metropolitan Detention Center. He's maintained his innocence amid an avalanche of civil lawsuits over the past year and pleaded not guilty to all charges.
Combs has lost two bids to be released on bail and is appealing once again for his release on a $50 million bond.
Combs may be facing new allegations from 120 male and female accusers who plan to file civil lawsuits against the media mogul, according to Texas-based lawyer Tony Buzbee.

His clients, some of whom were minors when the alleged abuse took place, accuse Combs of "violent sexual assault or rape," "facilitated sex with a controlled substance," "dissemination of video recordings" and "sexual abuse of minors," Buzbee said during a Tuesday press conference.
