The typical playbook for a defense lawyer representing a celebrity facing damaging accusations often features a sharply worded denial, promises to eventually reveal all at trial, and perhaps a strategically placed tabloid pushback story.

But lawyers defending the music mogul Sean Combs against a cascade of civil sexual misconduct claims have opened up a new strategic front: TikTok.

On Tuesday, the singer Dawn Richard filed a new lawsuit against Mr. Combs, accusing him of threatening and groping her. Mr. Combs’s representatives responded with a somewhat traditional statement that called the lawsuit a “series of false claims” brought “in the hopes of trying to get a payday.”

Then Teny Geragos hit TikTok. “All right, here we go again, Diddy sued by a former bandmate; I’m his lawyer and here’s why you should care,” Ms. Geragos, a member of the Combs defense team, said in a TikTok posted on Wednesday.

Employing a popular format in which a creator speaks in front of various screenshots that help illustrate a point, Ms. Geragos walked viewers through several examples of Ms. Richard, who performed with the groups Danity Kane and Diddy — Dirty Money, expressing support for Mr. Combs. She pointed — literally — to friendly text messages between the plaintiff and defendant in 2020 discussing a possible future collaboration and played a clip from a video interview in which Ms. Richard spoke positively about her time working with Mr. Combs. One of the mogul’s sons, Justin Combs, shared the video to his Instagram.

“We want to be able to respond to allegations where people are forming opinions,” Ms. Geragos said in an interview, noting that she is in her 30s and has grown up around social media. “I see where all of the misinformation spreads. I see it happening on people’s phones and in short one-minute clips.”
