Homeland Security Contacts Ex - Stylist In Human Trafficking Probe

The federal R . Kelly investigations are expanding -- agents specializing in human trafficking cases have now reached out to Kelly' s former stylist , who has ties to a couple of the singer ' s exes.

Sources close to celebrity stylist Kash Howard tell TMZ .. . Dept. of Homeland Security agents contacted Kash Wednesday and wanted to schedule a sit - down with her . It appears the call was prompted by a video that popped up all over YouTube this week.

In the video , Kash is behind the wheel of a car with 2 of Kelly' s ex- girlfriends , Halle Calhoun and Vonecia Andrews , as they talk to a media outlet about their relationships with the singer . Vonecia , aka Vee , was sobbing throughout the video , which our sources say Kash recorded last year.

We reached out to Kash , and she says , " Mr . Kelly hired me as his personal Fashion Stylist where I provided wardrobe direction for concerts , album cover shoots , and special appearances. Our professional relationship along with all communication ceased in March of 2017 . "

She also tells us she was only in the video because she was offering moral support to Halle and Vonecia.

As for Kelly' s legal battle , Kash says , " Mr . Kelly faces very disturbing charges. And while I have never personally witnessed any wrongdoing, I support those in search of the truth . "

TMZ broke the story ... the feds have 2 separate U . S. Attorney ' s Office investigations going , and will meet with Joycelyn Savage ' s parents , who say they have " physical evidence " to turn over.

We ' re told DHS also reached out to the Savages , and agents are in contact with Kash ' s attorney to set up the meeting with her.

Kelly' s attorney , Steven Greenberg ' s reaction to the investigation is.

 " That ’s their job . But just because they are looking into something, certainly nobody should conclude that they have any evidence of any wrongdoing or a crime was committed . ”
