From Emmy Rossum to Tiffany Marie Brannon: Meet Justin Siegel’s Wives

Justin Siegel, a prominent American entrepreneur and music executive, has captured public attention not only for his accomplishments in the business and music industries but also for his high-profile romantic relationships.

Born on August 25, 1981, in Boca Raton, Florida, Siegel is of Caucasian descent. However, limited information is available about his religion, family background, or siblings.

He holds a degree in sociology from the University of Massachusetts and furthered his education in music business and production at Berklee College of Music. Throughout his career, Siegel has been recognized for his work in the telecommunications industry and as the founder and managing partner of ATX Angel, LLC.

Siegel has been married twice. His first marriage was to actress and singer Emmy Rossum, widely known for her role in Shameless. The couple secretly tied the knot on February 17, 2008, keeping their union private until their separation in August 2009.

Siegel filed for divorce the following month, citing irreconcilable differences. The divorce was finalized on December 28, 2010. The marriage did not produce any children.

In 2014, Siegel began dating Tiffany Marie Brannon after being introduced on a blind date arranged by a mutual friend. They were married on September 27, 2018, at St. Andrew’s Church in Mells, England.

As of today, the couple remains married, with no public records indicating they have children. Siegel is not known to have children from any of his relationships.

Now 43, Justin Siegel continues to thrive professionally while maintaining a relatively private personal life. His relationships, particularly with Emmy Rossum and his current wife, Tiffany Brannon Siegel, have remained notable elements of his public persona.

Emmy Rossum

Emmy Rossum, born Emmanuelle Grey Rossum on September 12, 1986, in New York City, is a celebrated actress and singer-songwriter, best known for her portrayal of Fiona Gallagher on the acclaimed television series Shameless (2011–2019).

Her artistic journey began early, as she performed with the Metropolitan Opera as a child. She later earned critical praise for roles in films such as Mystic River (2003), The Day After Tomorrow (2004), and The Phantom of the Opera (2004). In addition to acting, Rossum has showcased her musical talents with two albums—Inside Out (2007) and Sentimental Journey (2013)—demonstrating her creative range.

Rossum’s relationship with entrepreneur and music executive Justin Siegel began in 2007. The couple secretly married on February 17, 2008, keeping their union private and continuing to appear as merely dating in public. Their secret was so well-guarded that news of the marriage only surfaced during their eventual split.

By August 2009, rumors of their separation began to circulate, and Siegel filed for divorce on September 25, 2009, in Los Angeles Superior Court, citing irreconcilable differences. He initially sought spousal support and divorce costs, but the court denied both requests.

Their divorce was finalized on December 28, 2010. As part of the settlement, Rossum retained their Beverly Hills home, jewelry, and personal effects, while Siegel received a $57,500 equalization payment, an $11,200 security deposit, and a Mercedes.

Speculation around the breakup intensified when Rossum was spotted with Counting Crows frontman Adam Duritz in September 2009, though neither Rossum nor Siegel publicly confirmed any infidelity. The timing of events, however, fueled tabloid interest.

Reflecting on the experience in a 2012 InStyle Hair interview, Rossum said, “Everyone messes up in relationships and has peaks and valleys in their personal lives. When I realized it wasn’t the end of the world and I would keep on standing, I knew it was going to be OK.” Their marriage lasted just 19 months but remains a significant chapter in both of their personal histories.

Following her divorce, Rossum found lasting love with writer and director Sam Esmail, whom she met while working on the 2014 film Comet. The couple married in May 2017 and now have two children: a daughter born in May 2021 and a son born in April 2023.

Tiffany Marie Brannon Siegel

After his divorce from Emmy Rossum, Justin Siegel found love again with Tiffany Marie Brannon Siegel—a woman known for her rich background in literature and the arts. Their story began in 2014 with a blind date set up by mutual friend Lisa Spies at Soho House in West Hollywood.

According to a Wedding Style Magazine feature, the match was sparked during Tiffany’s sister’s wedding, where—after a few glasses of champagne—Tiffany casually asked for a “nice guy.” Lisa delivered, and though Siegel was initially hesitant, his mother urged him to give the date a chance.

The chemistry was instant. The couple bonded over warm chocolate chip cookies and deep conversation, talking for four uninterrupted hours until they were the last guests remaining. Tiffany’s intelligence, wit, and shared interests quickly endeared her to Siegel, bringing a renewed sense of connection into his life.

Their relationship, though loving, wasn’t without its ups and downs. After a brief separation and an earlier, unfinalized engagement, Siegel officially proposed on April 15, 2018, during a romantic moment in Malibu. The couple married later that year, on September 27, 2018, at the picturesque St. Andrew’s Church in Mells, England, with a reception following at the elegant Babington House in Somerset.

Their honeymoon was an epic journey, including a month-long African safari and a relaxing week spent in Mykonos and Santorini before returning to the UK. Since then, Justin and Tiffany have continued to build a strong and creative partnership.

Although they have no publicly known children, their relationship is marked by shared adventures, mutual respect, and a deep appreciation for one another’s passions—hers in the arts and his in entrepreneurship.
