Matthew Bellamy has filed for divorce and is asking a Los Angeles court for full legal and physical custody of his two young children, invoking a premarital agreement and signaling a dispute that will shape custody and financial questions as the case proceeds.

Muse lead singer Matthew Bellamy filed the petition on Aug. 12, citing irreconcilable differences and invoking the couple’s premarital agreement on financial matters, while the papers did not list a date of separation or disclose the prenup’s specific dollar terms. He seeks sole legal and physical custody of the two children the couple shares, a daughter born in 2020 and a son born in 2024, rather than a joint parenting plan. That combination of custody requests and the prenup invocation puts both parenting time and money squarely on the table from the start.

Bellamy had already signaled there was trouble before the filing became public, telling The i Paper that the couple separated “last summer” under unusual conditions and that the split forced him to rethink priorities. He described the circumstances as out of the ordinary and framed his actions around protecting his children and stabilizing the home. Evans, who is a model and actress, has not issued a public response to the court papers as of the filing.

“Because it’s one of those situations that involves something that people wouldn’t normally think it is. It was a set of really unexpected circumstances.”

In that same interview Bellamy was explicit about refocusing on family life, saying the experience had “thrown me off” and required him to prioritize looking after the kids and building consistency at home. Those comments mirror the language in the legal petition, where his request for sole custody suggests he believes he can best provide the stability he describes. California courts usually prefer arrangements that let both parents spend meaningful time with children, so Bellamy will need to show why shared custody would not meet the kids’ best interests.

“It’s the kind of thing no one really prepares for in life. It threw me off, and I had to prioritize [looking after the kids] and creating stability at home.”

On the financial front, Bellamy invoked the prenup and indicated that Evans could receive spousal support under its terms, while also asking the court to deny any spousal support claims in his favor, signaling he does not plan to claim financial dependence on her. He acknowledged in the petition that he has “yet to determine the full nature and extent” of the couple’s separate assets and obligations and left open the possibility of amending the petition as more information emerges. That reservation keeps open questions about community property, debts, and whether additional financial claims will follow.

High-profile separations involving children often draw sustained attention and can become protracted when two public figures dispute custody or finances, and this case has the same elements that make a long legal fight possible: young children, public profiles, and a prenup that frames the financial debate. The couple met in 2015, reportedly on the set of a Muse music video, Bellamy proposed during a vacation in Fiji in December 2017, and they married in 2019, with this being Bellamy’s marriage following other well-known past relationships. The outcome will shape day-to-day life for their daughter and son for years to come.

Bellamy’s decision to request both legal custody, which covers major decisions about schooling, health and religion, and physical custody, which determines daily residence, puts the burden on him to present evidence the court will accept. The petition does not spell out the detailed reasons behind his sole-custody claim, so judges will expect more than general statements about stability when weighing such a significant change from the usual shared arrangements. Evans’ next move—whether to contest custody, rely on the prenup, or negotiate a different outcome—will determine how public and prolonged the dispute becomes.

Their two children are very young, meaning whatever the court orders will shape their routines and upbringing for years, and the case could serve as another reminder of how complicated custody and money become when both parents have public lives. For now, Bellamy’s filing sets a clear position: he has asked for full authority over parenting decisions and daily care and has signaled he will not be seeking spousal support, while leaving room to amend financial claims. The court will sort the facts, weigh evidence, and decide whether sole custody is warranted under California law, and two young lives are at the heart of that decision.
