Arnold Schwarzenegger’s love-child Joseph Baena, born after he had an affair with housekeeper Mildred Patricia Baena, was reportedly not invited to half-brother Patrick’s wedding.

The 31-year-old White Lotus sensation tied the knot with Abby Champion on September 6 in Coeur d’Alene, Idaho.

However, the 27-year-old bodybuilder — who is the same age as half-brother Christopher Schwarzenegger — was not on the guest list, according to a Monday report from TMZ.

Arnold, 78, shares daughters Katherine, 35, Christina, 34, and sons Patrick and Christopher with ex-wife Maria Shriver, 69.

Joseph, who has followed in his dad’s footsteps with bodybuilding and acting, didn’t know that Arnold was his father until he was 13-years-old.

The news became a nationwide scandal in 2011.

Arnold and Maria announced their separation on May 10, 2011.

At the time, they released a joint statement that read, ‘This has been a time of great personal and professional transition for each of us.

‘After a great deal of thought, reflection, discussion, and prayer, we came to this decision together.’

The former couple noted that they had been living apart and navigating ‘the future of our relationship.’

Together, they said, ‘We are continuing to parent our four children together. They are the light and the center of both of our lives.’

Just one week later the Terminator star came clean about his marital affair.

He said in a statement to the Los Angeles Times: ‘After leaving the governor’s office I told my wife about this event, which occurred over a decade ago.

‘I understand and deserve the feelings of anger and disappointment among my friends and family.

‘There are no excuses and I take full responsibility for the hurt I have caused. I have apologized to Maria, my children and my family. I am truly sorry.’

Maria filed for divorce on July 1, 2011.

In a December 2017 interview with Men’s Journal, the former California governor opened up about his headline-making affair.

‘I can beat myself up as much as I want — it’s not gonna change the situation. So the key thing is, how do you move forward? How do you have a great relationship with your kids?’ he was quoted in the article.

He added, ‘You can’t go back — if I could, in reality, be Terminator, of course I would go back in time and would say, “Arnold … no.”‘

And he noted, ‘You know, it’s always easy to be smart in hindsight. That’s not the way it works.’

Joseph reportedly does not have a relationship with his half-siblings, as evidenced when they all attended their dad’s FUBAR season two premiere in June.
