In new pics, 35-year-old Williams and 37-year-old Kelly were snapped watching a movie together on Monday night in West Hollywood, California. Both dressed down for the outing, Williams wearing a black hoodie and a baseball cap, while Kelly also sported a baseball cap, a sweatshirt and a black coat, despite the heat.
Williams and Kelly both starred in Lee Daniels' The Butler in 2013, though the two do not have any scenes together. In January, Kelly Instagrammed a photo of the two hanging out in Paris alongside a mutual friend, where according to multiple reports, Williams and Kelly were working on a video game project.
"Last meal en Paree post 15hr workday! Time for silly," Kelly wrote.
ET confirmed that Williams filed for divorce from Drake-Lee in April, citing "irreconcilable differences" as the reason for the split. They have two children together -- daughter Sadie and son Maceo.
In JAY-Z's mini-documentary that the rapper released on Monday, titled Footnotes for 4:44, Williams as well as other celebs talk about their experiences with love and the pressure of being in the public eye. The Grey's Anatomy star candidly addressed rumors of infidelity.
"I was in a relationship 13 years, 13 real years, not 5 years, not 7 years -- 13 years," Williams says. "All of a sudden, mother f**kers are writing think pieces that I somehow threw a 13-year relationship -- like, the most painful experience I’ve had in my life, like, with a person I’ve loved with all of my heart -- that I threw a person and my family in the trash because a girl I work with is cute."
