Stacey and Thiemo married in Germany in September 2007, according to divorce filing coverage. Court documents obtained by TMZ, and covered by Bossip, show they separated in August 2023, that Thiemo filed for divorce in early December 2024, and that a final decree was entered on December 16, 2024. They separated after roughly 16 years of marriage, and the divorce was finalized about 17 years after the wedding.
Stacey has said the two of them learned the divorce was final while on a Christmas 2024 trip to Mexico with their daughter, Arabella. "We just looked at each other. I think we both knew it wasn't the end of us," she said.
By February 5, 2026, Stacey told People they were dating again and that Thiemo had moved back into the family home she shares with their daughter, Arabella. "My ex-husband and I are dating, and it feels really, really like this incredible blessing to be able to have a second chance with someone that you've known for 20 years, the father of your child, one of your best friends on this earth," she said, describing their new arrangement as "back together right where we belong."
TheWrap reported in October 2024 that Thiemo was Senior Vice President of Sales and Operations at Audi of America. Stacey has described him as private and largely outside the show.
