Sara Foster And Her Ex Take Healthy Co-Parenting To The Next Level With Their Living Arrangement

Co-parenting isn't easy. Every divorced or separated couple must decide the best, healthiest way to cooperate as parents — and it's different for every family. However, "90210" alum Sara Foster and her ex-partner Tommy Haas have opted for a somewhat unorthodox co-parenting method: co-habitation. During an appearance on Kristin Cavallari's podcast "Let's Be Honest" in June 2026, Foster discussed her "interesting" relationship with Haas, whom she explained is almost always on the road but returns to their Los Angeles home. "We have breakfast when he's in town — we have breakfast and dinner with our kids every day," Foster said. "It's not for everybody, but there's something to be said about slowly transitioning." Foster and Haas, who share two daughters, ended their 20-year relationship in 2024.

The "Nobody Wants This" producer went on to praise Haas, stating that their relationship dissolved because of a "collective shift" rather than a singular dramatic event. "This guy has got so much integrity. You will never meet anyone that has a bad thing to say about him," Foster told Cavallari of the former tennis pro. "He has real integrity. He's not a social climber, he's not a user ... He's a great guy." Unlike the parallel parenting approach (which has many pros and cons), Foster and Haas have uniquely set their prior relationship aside in order to parent as a team. While their strategy certainly won't work for all exes, according to Foster, the slow transition is serving their children well. That's great news, as many former couples find themselves having to deal with overwhelming parental guilt.

Plenty of celebrity couples have co-parenting down to a science. Some couples, like Naomi Watts and Liev Schreiber, and Jennifer Garner and Ben Affleck, have remained friends with their ex-partners and regularly spend time with their shared children together. Others, such as Jennifer Lopez and Marc Anthony, have had to overcome personal issues in order to co-parent effectively. But, for pairs like Sara Foster and Tommy Haas, their co-parenting style is completely intertwined. Similarly to them, Demi Moore and Bruce Willis also parented under the same roof after their split.

Moore and Willis divorced in 2000, going on to parent their three daughters as a team with their respective new partners. They even chose to quarantine together in 2020, with Moore telling Naomi Campbell on "No Filter" that it was an "incredible opportunity." "There's been a lot of challenges and a lot of tragedy with this pandemic, but I also think there's been a lot of gifts and blessings. I personally feel like I was really grateful for things slowing down and the time that we had," Moore said. Moore's outlook on parenting is remarkably similar to Foster's, showing that parenting after a break-up can be a positive experience for some. While co-habitation still isn't a popular co-parenting strategy, it's interesting to see how some Hollywood couples have begun to embrace the unique method.
