The two, who've both accused Harvey Weinstein of sexual assault, are walking amongst thousands of females in Rome for a women's parade on International Women's Day.
McGowan and Argento are seen holding a banner with the hashtag #WeToogether ... a spin-off the #MeToo movement that Rose is given tremendous credit for shining light on.
This isn't the first time we've seen them hanging out.
In November, McGowan posted a photo of them together with Annabella Sciorra, another Weinstein accuser, with the caption, "Magical moments with @asiaargento & @iamannabellasciorra #WomenRise #Survivors #ROSEARMY."
As The Blast reported, the three women were among the first, and the most outspoken, of Weinstein’s accusers.
