The Terminator star reached his new milestone last Thursday, and it turns out he spent the day with his loved ones, including estranged wife Maria Shriver. 

On Monday, his son Patrick Schwarzenegger posted a photo to Instagram showing that he marked the special occasion with Shriver, 64, and the four children they share together.

Schwarzenegger has a fifth child, Joseph Baena, who he fathered with his housekeeper at the time, Mildred Patricia “Patty” Baena. Joseph, 22, wished his father a happy birthday in a rare throwback picture last week. 

Meanwhile, Patrick, 26, captioned the family photo, ‘I’m trying so hard to smile… damn wisdom teeth SMH… Happy birthday pops! Love u’ with his siblings Katherine, 30, Christopher, 22, and Christina, 29. 

Despite filing for divorce after 25 years of marriage back in 2011, recent reports have suggested that Schwarzenegger and Shriver are still legally married as they have never finalized their divorce proceedings.

Shriver filed for divorce after learning that Schwarzenegger had fathered a child – Joseph – with their housekeeper Mildred.

The child was on October 2, 1997, only a few days after Shriver gave birth to the couple’s fourth child, Christopher. 

But it wasn’t until May of 2011 that it was revealed that the housekeeper’s child was his.
