Katherine Schwarzenegger joined the Mom's club!

Yes, Katherine had delivered her first child with Chris Pratt. Katherine's brother Patrick Schwarzenegger announced through an exclusive video. The 26-year-old said in the video that the couple and the little one are doing great.

Patrick was spotted in Santa Barbara, California on Aug. 9. When the Scouts Guide to the Zombie Apocalypse star was congratulated for her sister becoming a mother, he thumbs up to the reporters. He also flaunted the gift in his hands on the camera that had a decorative pink ribbon. Then, the actor settled down in his car.

However, it is not sure if the gift was packed in pink for the baby or his sister. While Patrick didn't confirm the delivery date of the baby, a source confirmed to ET that on Aug. 7 Pratt's vehicle was seen at the St. John’s Hospital.

The hospital is located in Santa Monica, California. Katherine's mother Maria Shriver and father Arnold Schwarzenegger along with Christina and Christopher visited the 30-year-old's house. The Schwarzenegger's family left the house and Arnold was spotted in his iconic style of smoking a cigar while heading towards his car.

The 73-year-old actor was sporting casual shorts and a blue t-shirt that reads the USA. The next day, Maria along with the clan was captured visiting the new mother's place once again. However, this time Arnold went for a bike ride and ran into his daughter Christina who is 29-year-old and Patrick at Caffe Luxxe.

There was a delivery van that dropped flowers on Aug. 8 at Schwarzenegger’s residence. The Guardians of the Galaxy star already has a seven-year-old son with his ex-wife. The 40-year-old actor divorced Anna Faris in 2018 and married Katherine in June 2019.

The wedding took place in Montecito, California that involved only close friends and family members. In April, the couple disclosed the pregnancy, and recently, they shared a picture on Instagram that displayed the baby bump.

"Chris and Katherine are extremely happy to be pregnant with their first child. The couple knew going into their relationship that having kids together was important to them, so when they found out the news, they were extremely happy," the source said.

The source further revealed that the initial months of Katherine's pregnancy were occupied with the promotion of her latest book. However, now she has devoted all the time to the baby's arrival while Pratt is extremely excited to share their first child.
