Jessica Alba has reportedly retained a divorce lawyer amid her split from Cash Warren, but they are still "friends and all about the kids".

The 43-year-old actress is said to be moving forward with the pair's separation, after it was reported last week the showbiz power couple had split up after 16 years of marriage, but they are expected to "remain close".

A source told PEOPLE: "No matter what's going on right now, it seems they will remain close.

"If they're filing for divorce, it's not because of some hateful drama. They still look happy together.

"Jess has mentioned over the years though that it's hard to keep the spark."

Last week, insiders claimed to TMZ that Jessica and Cash - who have daughters Honor, 16, and Haven, 13, and seven-year-old son Hayes - are "about to call it quits with a divorce filing" and they are "moving forward" with those plans.

It was also thought the couple had only just "recently separated", but it is "unclear" what led them to this stage.

Jessica and Cash have both been spotted without their wedding rings in recent weeks, including when the 'Dark Angel' star attended a pre-Golden Globes party at the Chateau Marmont in Hollywood without Cash earlier this month.

The pair were last seen together in public in November when they attended a basketball game together.

They initially met on the set of 'Fantastic Four' in 2004, when Jessica was starring as Sue Storm in the Marvel movie, and Cash was serving as a director's assistant on the project.

In 2021, Jessica admitted that becoming parents had changed their marriage, and joked they had become "roommates".

She said on Instagram series 'Before, During and After Baby': "It's all rosy for two and a half years. But then after that you become roommates.

"You're just going through the motions. You have the responsibilities; it's a lot of, like, checking the boxes, right?"
