Bourdain was found dead June 8 in his hotel room while on location shooting an episode of his hit travel show in France.
McGowan posted a heartwrenching video this morning after news broke of Bourdain's death. Argento also took to social media to release a statement calling Bourdain "my love, my rock, and my protector."
Argento and the award-winning television host have been linked since 2017. She recently directed an episode of Bourdain's CNN travel show "Parts Unknown."
McGowan and Argento are both ardent activists for women's rights and have been two of the most outspoken of Harvey Weinstein's accusers. Over the last few months, Bourdain has fiercely supported Argento and McGowan in their efforts to take down the shamed movie mogul.
The "Kitchen Confidential" author was spotted out to dinner in NYC with McGowan in November, during the height of the Weinstein scandal.
