Uh oh! This sounds like it's getting nasty...

Amber Heard filed for divorce from Johnny Depp on Monday, and requested spousal support from the actor in the documents. Now, the Pirates of the Caribbean star has filed his own papers asking a judge to reject his estranged wife's financial request. The actor is worth an estimated $400 million, and the couple didn't have a pre-nup, so this is bound to get ugly!

This split couldn't come at a worse time, either. The father-of-two is mourning the loss of his beloved mother Betty Sue Palmer, who died aged 81 after a long illness just three days before the divorce petition was filed.

So what was the straw that broke the camel's back? The eccentric A-lister's family "hated" the Rum Diaries beauty! According to TMZ, Depp's two teenage children, his two sisters, and his mother all despised the blonde bombshell and thought that she "treated him like c**p." They also thought that she was after his money and using his star power to further her own career.

Johnny moved his mother into the couple's Los Angeles mansion as her health deteriorated, and it was all downhill from there. "The tension was palpable. We're also told that, before Betty Sue moved in, she only saw her son once from the time he married Amber. And both Betty Sue and Johnny blame her for keeping them apart so she'd have full control," a source told the website.

At least they didn't have any kids together!
