Hilary Duff and her ex-husband, Mike Comrie, may have finalized their divorce, but the question remains: Why did the actress end up paying the wealthy heir nearly $2.5 million in their split? 

The Los Angeles Superior Court confirmed to Us Weekly on Tuesday, February 2, that the former couple finalized their divorce on January 28. They first split more than two years ago.

According to TMZ, which obtained the documents, Duff walked away with their mansion in Beverly Hills and another property, while Comrie got to keep the Bentley, the Mercedes and jewelry. The Younger star was also reportedly ordered to pay the former NHL player $2,408,786 to settle their split financially, which could be considered odd given that Comrie comes from a multimillionaire family. (The former athlete's father, Bill Comrie, founded a Canadian retail company and is worth hundreds of millions of dollars.)

Us Weekly's legal counsel says Duff is likely paying her ex in order to keep their Beverly Hills property. As recalled, the two signed a prenuptial agreement when they married in 2010.

Duff and Comrie announced their separation in January 2014 after three years of marriage. The "Sparks" singer was initially hopeful for a reconciliation, but she resolutely closed the door last February after her ex, 35, drunkenly hit on a waitress. Duff filed for divorce a day after his behavior made headlines.

According to the divorce docs, the exes will share joint custody of their 3-year-old son, Luca, with neither party receiving spousal support. 

Despite the drama, Duff told Ellen DeGeneres last Friday, January 29, that she and her ex remain friendly

"We are good friends and we laugh a lot," she said. "And we have a great communication and we share pictures when one is not with Luca. He’s great, we are great and we keep on trucking."
