“WOW,” she wrote one day after her former mentor was accused of raping a teenager in 2000.
She added the word “WAIT” along with a shocked-face emoji in another slide.
Although the posts came on the heels of the refiled civil lawsuit against Jay-Z and Combs, Brown did not reference either.
She also didn’t offer an explanation about the meaning behind her messages.
Page Six reached out to reps for Jay-Z and Brown for comment but did not immediately hear back.
Brown, 46, has previously collaborated with Jay-Z on several songs, including her 1996 track “I’ll Be.”
She notably took to social media in October to slam claims she had signed an NDA about her relationship with the 24-time Grammy winner.
“In icon business! Miss me wit that fake news,” Brown wrote, according to Billboard. “NDA? Ain’t a MF alive could stop my story. NDA on my s–t gon’ run 100 mill.”
Brown also shared a screenshot of a YouTube video claiming she was “break[ing] her silence” on Jay-Z.
“Stop playin’ wit my name, dyin’ for a comment,” she wrote at the time. “Can’t spin me with the sucker s–t to take Hov down. Betta ask bout’ the cloth I’m cut from.”
Brown then seemingly shared her support for the Roc Nation founder, 55, writing, “Y’all want me to be anti-Hov so bad. FOH.” (The acronym means “F–k outta here.”)
The “Ill Na Na” rapper’s cryptic posts came after Jay-Z was named in a civil lawsuit on Sunday and accused of raping a teenage girl with Combs at an MTV Video Music Awards afterparty in 2000.
