Ewan McGregor's split with his wife of 22 years was explosive enough already after it was revealed he had left her for Fargo co-star Mary Elizabeth Winstead.
But now, things have heated up even further, with the Moulin Rogue actor's daughter taking to social media to slam him for leaving her "goddess of a mother".
Clara McGregor didn't hold back when she posted a photo of mother, Eve Mavrakis, on Instagram yesterday.
The incident started out innocent enough, with the 22-year-old uploading a picture of Eve lying on the beach in a bikini, looking undoubtedly younger than her 52 years.
"My mother, ladies & gentlemen • 50 is the new 30 apparently," Clara wrote in the caption.
However, things became tense when a fan jokingly commented, saying: "Good to know you have the smoke show genes... keep her away from your boyfriends".
Clara's carefree post quickly turned hostile when she seemingly labelled her 47-year-old father an "a**hole" in her response, writing: "nah I keep her away from a**hole men who leave my goddess of a mother".
It's not the first time Clara has hit out at her father for his relationship with 34-year-old Mary, who first hit the acting scene with her role as Jessica Bennett on the NBC soap opera Passions.
Last year, she took to social media to label the Scott Pilgrim vs. the World star a "piece of trash".
When an Instagram account dedicated to Mary called her "beautiful", the model lashed out in the comment section, writing: "Most beautiful and talented woman on earth??? ??? oh man y'all are delusional. The girl is a piece of trash :) x".
In an interview with the Times, Ewan's daughter later claimed she regretted the comment, stating: "It wasn't the most mature way to go about things, but I was angry and upset. There had been a lot building up to it and a lot to deal with — not to make excuses or anything — but, yeah, it wasn't my finest moment.
"I kept being tagged in this photograph and I was seeing negative things about my mom. I said how I felt and I didn't want to apologise for it. It wasn't the right way to go about things, but it's a hard thing to wrap your head around when you feel you had this idea of what the family unit is and then to have that shift. It's very weird."
However, her new comments on Instagram perhaps show that she hasn't forgiven her father for breaking up their family quite yet.
The actor filed for divorce in January 2018, three months after he was spotted kissing Mary in a London cafe in October 2017. However, the date of separation on the divorce documents stated he had been estranged from Eve since May 2017.
Mary Elizabeth was previously married to director Riley Stearns, but the couple also announced their split in May 2017 after seven years of marriage.
Riley first announced the divorce in a heartfelt Instagram post, which read: "While we will still be in each other’s lives we will no longer be living those lives together. We still love each other very much but we’re different people with different paths and different futures. I can’t wait to see where we both end up. I'll always love you, Mary."
However, the post was deleted after pictures of Mary kissing Ewan appeared in the media, potentially suggesting the break-up was no longer friendly.
