Arnold Schwarzenegger’s son Joseph Baena not invited to half-brother Patrick’s wedding: report

Joseph Baena was allegedly excluded from half-brother Patrick Schwarzenegger’s wedding.

Joseph — who is Arnold Schwarzenegger’s 27-year-old son from his affair with housekeeper housekeeper Mildred Baena — “wasn’t invited” to Patrick, 31, and Abby Champion’s Sept. 6 nuptials in Idaho, TMZ reported on Monday.

Sources told the outlet that Joseph was left off the invite list since he “has no relationship with that side of the Schwarzenegger fam.”

The Post has reached out to reps for Joseph, Arnold and Patrick for comment.

Patrick’s famous parents, Arnold, 78, and Maria Shriver, 69, and his siblings, Katherine, 35, Christina, 34, and Christopher, 27, attended the wedding.

Other guests included Champion’s parents, Laura and Greg Champion, Patrick’s brother-in-law, Chris Pratt, and Patrick’s “The White Lotus” co-star, Jason Isaacs.

Patrick and Champion, 28, tied the knot at the Gozzer Ranch Golf & Lake Club, which overlooks Lake Coeur d’Alene.

The groom was pictured in a cream tuxedo and black dress pants, while the bride stunned in a sleeveless cream gown and floor-length veil.

Arnold secretly welcomed his look-alike son with Mildred, 64, during his 25-year marriage to Shriver. The journalist filed for divorce from Arnold in 2011 after learning of his affair.

The “Terminator” actor told People in 2023 that his infidelity is his “f–k-up.”

“We always made it very clear that the kids should not suffer because of [my affair],” Arnold added.

Joseph seemingly has not maintained relationships with Arnold and Shriver’s children.

In June, Arnold was joined by all five of his kids at the “FUBAR” Season 2 red carpet premiere in LA, but Joseph was snubbed by his four half-siblings.

Arnold first took pictures with Katherine, Christina, Patrick and Christopher, and then posed for separate photos with Joseph.

Meanwhile, in 2023, a source told Page Six that Joseph has a good relationship with Arnold but isn’t close with the other children.

“The other kids don’t love Joe,” the insider alleged.

“It’s a shame as he’s a really good kid, and Arnold has always treated him like all his other kids — very fairly. But for whatever reason, the other kids take [the affair] out on Joe,” the source added.

In March, Joseph explained why he goes by his mother’s surname.

“I think the main thing is I’m trying to do things on my own,” he told “Good Morning Britain.”

“My family is very big in supporting from afar and not being so hands-on, I really appreciate that. I think it’s really important growing up as a man to do things on your own. To figure it out, that’s what I’ve been doing,” he added.
