Paulina Porizkova goes Instagram-official with new boyfriend: Who is Jeff Greenstein?

Paulina Porizkova is making her new romance official.

The 58-year-old supermodel took to Instagram on Wednesday to share a photo with two iPhones, each with a hand about to delete the Raya app, which celebrities and influencers use to date and network.

On the left hand, Porizkova tagged the account of television writer and director Jeff Greenstein.

"This is what commitment looks like these days. Deleting the dating app on which we met. Thank you, [Raya] and goodbye," Porizkova captioned her post, while tagging her new boyfriend alongside a red heart emoji.

In March, the former "America's Next Top Model" judge opened up about testing the waters of the dating pool while on the "HollywoodLife Podcast."

While chatting about the book "Us" by Terrence Real on the March 14 podcast episode, she said, "I was reading it when I was single, and I thought, 'The next man I meet where I feel like the potential for a relationship is going to go somewhere, I'm going to make them read this book before we get anywhere for real.' And so I can say, I've just handed that book up to somebody."

Porizkova noted during the chat that back then, the relationship was still "in the early days." After the then-mysterious man read the book, she said it prompted "the most amazing conversations about ourselves and where we are going and what we want."

But now that the world officially knows who the Czech-born model is dating, who is Jeff Greenstein?

He's worked on major television shows from the 1990s and 2000s

Greenstein snagged his first gig in Hollywood working on the sitcom "Dream On," which ran on HBO for six seasons between 1990 and 1996. According to his IMDb page, Greenstein is credited as a writer, producer and story editor on the show, which was created by "Grace and Frankie" co-creator Marta Kauffman and "Episodes" co-creator David Crane.

While still working on "Dream On," Greenstein was brought on to support the inaugural season of "Friends," which was also created by Kauffman and Crane. On top of writing four episodes, Greenstein is also credited as a supervising producer of the American sitcom series.

But Greenstein's TV work doesn't stop there. He was a head writer for the first six seasons of "Will & Grace," where he eventually became comedy series's showrunner for seasons five and six. He's also credited as a writer, executive producer and director for "Desperate Housewives."

His most recent television work focuses on directing

Some of Greenstein's most recent credits include directing episodes for a variety of comedy series. Those include "Mom" starring Allison Janney and Anna Faris, "The Odd Couple" with Matthew Perry as well as "The Neighborhood" starring Cedric the Entertainer and Max Greenfield.

He's received numerous awards and nominations

Greenstein has been the recipient of several awards and nominations throughout his career, including the 2000 Emmy Award for Outstanding Comedy Series as co-executive producer of "Will & Grace." He also received six nominations for his work on the show, as well as a writing nomination at the 2001 Emmys Awards.

On top of that, Greenstein also earned two Emmy nominations for "Friends," four CableACE nominations for "Dream On" and three PGA Awards nods for "Will & Grace," among various other nominations.

He's a fan of film photography

Now, Greenstein produces and co-hosts the "I Dream of Cameras" podcast alongside Gabe Sachs, who has written episodes for shows like "Freaks and Geeks" and "90210." It's a podcast that focuses on camera collecting and the details behind vintage cameras.

On his Instagram, Greenstein notes that he's a writer who's worked on various big TV shows but that he's also a photographer who snaps images of buildings and plants. His feed is also full of scans of his own film photography work, where he shows off his talent by photographing architecture, objects and landscapes in black and white.
