McGregor split from Clara's mother Mavrakis in October 2017 after 22 years of marriage.
Ewan McGregor's daughter Clara has called out "asshole men" who left her "goddess" of a mother.
On Tuesday, the young actress posted a photo of her mother, Eva Mavrakis, showing off her bikini bod at the beach. "My mother, ladies & gentlemen," Clara captioned the pic. "50 is the new 30 apparently."
After a fan commented on the pic, "good to know you have the smoke show genes...keep her away from your boyfriends," Clara responded, "Nah I keep her away from asshole men who leave my goddess of a mother :)".
The model did not name anyone in particular in her response.
Previously, Clara has thrown shade at her father's new relationship. Back in July, Clara slammed McGregor's girlfriend, Mary Elizabeth Winstead, after a fan pointed out the actress' good looks.
"Most beautiful and talented woman on earth???" Clara said at the time. "Oh man y'all are delusional. The girl is a piece of trash."

McGregor split from Clara's mother Mavrakis in October 2017 after 22 years of marriage. The actor filed for divorce from the production designer the following January, citing "irreconcilable differences."
Despite many reports, it's unconfirmed whether McGregor began dating Winstead during his relationship with Mavrakis. Clara spoke about their relationship to The Times back in September and expressed how shocking it was to her and her family seeing Winstead and her father out together, kissing in paparazzi photos, just as the news of the split was settling in for them.
"We had already started dealing with it and trying to cope," Clara said. "It was incredibly surprising to me that they had gone out in public. The picture surfaced on my little sister's birthday, but my dad didn't know it was going to come out. He didn't want us to see that, but, you know, there were paparazzi following them around."
Clara has made it clear she has sided with her mother during the separation, but said the rift was "never one-sided" and "both were to blame." The 22-year-old also stressed that she's still "very close" with McGregor.
"I love him and I always will. The relationship's not going to end because of this," she said. "We are incredibly close and despite me strongly disagreeing with how he's gone about things, I'll always love him, and I hope he's happy, you know?"
