Whitney Cummings may not know Justin Baldoni personally … but that sure didn’t stop her from opining that she knows his type — and she thinks there were clearly warning signs that align with allegations in Blake Lively‘s recently filed complaint.

Here’s the deal … Blake sued costar Baldoni for sexual harassment and alleged he took part in a coordinated effort to destroy her reputation … all stemming from their work together on “It Ends with Us.”

Since news of the shocking complaint broke … Justin has been dropped by his talent agency … and a number of stars — including SAG and Sony Pictures — have expressed strong support for BL.

Whitney can officially be added to that list after the stand-up comic went scorched earth on JB in a nearly 5-minute-long TikTok … in which she attacked him on several fronts, including his preaching feminism.

Basically, WC says in her opinion, Baldoni was trying way too hard being so hardcore pro-feminism, which should have been a red flag, adding … “When guys fight for women’s rights — it’s how they get laid!”

Whitey also zapped Baldoni for having “women’s equality charity energy” — mentioning he was a part of multiple non-profits, adding … “If I was a bad person, what is the first thing I would do … start a charity.”

Among quips about his manbun and possible sunbathing habits … Whitney said she thought JB was the type of man who told women they look better without makeup … except when on the set of one of his films — in which case they better wear a ton.

We broke the story … Blake filed a lawsuit against Justin late last week … the lawsuit includes text messages between two public relations flacks who worked for Baldoni, scheming on how to take down Lively.
