MailOnline has contacted representatives for Ewan McGregor and Mary Elizabeth Winstead for comment. 

This isn’t the first time Ewan has surprised fans with secret baby news, previously revealing in 2011 that he adopted a girl. 

He told the New York Post that year: ‘My wife and four girls – 15, two 9-year-olds and a baby of four months – often come with me if it’s a holiday or my locations and their schedules allow. Sometimes we uproot them and put them in another school.’

Ewan shares Clara, and daughters Esther, 19, Jamyan, 20, and Anouk, 10, with ex-wife Eve, they split in 2017 and their divorce was finalised in August 2020. 

In July 2018, Clara fired verbal shots at Mary Elizabeth after a fan of the actress tagged her in a photo of Ewan and Mary sharing a kiss at a Vanity Fair Oscars party.

In the post’s caption, the fan had referred to Winstead as ‘the most beautiful and talented woman on earth’ – something Clara was more than ready to refute.

‘Most beautiful and talented woman on earth??? Oh man y’all are delusional. The girl is a piece of trash :),’ wrote Clara in the post’s comment section.

Soon after her reply, another Winstead fan urged her to ‘say it to [Winstead’s] face not [on] social media.’

They added: ‘It took TWO to undo this marriage. If a man OR woman is happy w/ their marriage no outside interference can destroy that!’

To the fan’s surprise, Clara firmly agrees with their assessment. ‘Yup it took two!! Mary & my father :),’ she wrote.

In an interview with The Times in August that year, Clara openly acknowledged the immaturity of her Instagram banter, but claimed that her rage was justified.

‘It wasn’t the most mature way to go about things, but I was angry and upset.’

According to Clara, there were things going on behind-the-scenes that became ‘a lot to deal with’ and eventually sent her over the edge.

‘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,’ she admitted.

She also explained that she kept ‘being tagged in the photograph’ and was ‘seeing negative things about [her] 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.’
