Katherine Schwarzenegger welcomes her first child with husband Chris Pratt

Katherine Schwarzenegger, 30, has welcomed her first child with husband Chris Pratt, 41. 

Katherine’ brother Patrick confirmed the birth to ET on Sunday, while at a market in Santa Barbara, CA.

‘They’re doing great — just got her a little gift,’ said the 26-year-old actor, who could be seen ‘carrying a package with a pink ribbon.’

Although Patrick did not disclose the baby’s gender or the exact date of birth, parents Maria Shriver, 64, and Arnold Schwarzenegger, 73, as well as the remaining Schwarzenegger siblings, paid a visit to Katherine and Chris’ residence on Friday.

Maria returned later that day to spend some more quality time with her daughter, who may or may not have given birth sometime that day.  

The couple’s pregnancy was confirmed by Maria on April 30, when Pratt appeared as a guest on her Instagram Live series #HomeTogether.

‘You’re gonna have another beautiful family member,’ said Shriver to Pratt at the time.

Less than a month later, Katherine was spotted for the first time with a visible baby bump, while leaving Maria’s home in the Pacific Palisades area.  

The baby happens to be Schwarzenegger’s first child, whereas Pratt shares a seven-year-old son with ex wife Anna Faris, 43. 

News of Katherine’s pregnancy came just 10-months after her wedding to Chris, which took place in June of 2019.

He had proposed to Katherine in January of 2019, less than a year after they began dating in June of 2018.  

Days prior to the birth of their newborn, the Jurassic World star uploaded a snapshot of himself and his pregnant wife with the caption: ‘Ready to pop, still don’t stop.’ 

In the photo, Katherine looked heavily pregnant in a black tank top and leggings as she posed prom style with Chris.

He continued: ‘Top of the mountain today. Kinda grateful it didn’t go down on the trail tho to be real.’

Chris and Katherine were first linked in 2018, after they were spotted canoodling in Santa Barbara, CA.  

Seven months prior, Chris filed for divorce from wife Anna Faris after eight-years of marriage, citing ‘irreconcilable differences,’ according to TMZ. They asked for joint custody of their son Jack who was five-years-old at the time.

Chris and Katherine made their first PDA in July of 2018, followed by numerous family hangouts with the Schwarzenegger’s and the Pratt’s, which were documented on social media.  

The couple did not confirm their relationship status until December of 2018, a little over a month after Chris’ divorce from Anna was finalized, as reported by E! News.

The confirmation came in the form of ‘Happy Birthday’ post from Chris to Katherine, which included a photo collage of the brunette beauty.

‘Happy Birthday Chief! Your smile lights up the room. I’ve cherished our time together. Thrilled God put you in my life. Thankful for the laughs, kisses, talks, hikes, love and care,’ wrote the Parks And Rec alum.

On January 9, Chris proposed to Katherine, which he proudly announced to his 28.8million Instagram followers. 

‘Sweet Katherine, so happy you said yes! I’m thrilled to be marrying you. Proud to live boldly in faith with you. Here we go!’ captioned Pratt.

He included a photo of himself and Katherine embracing that gave his followers a clear view of the giant rock on her finger. 

They moved in together shortly after getting engaged. 

Katherine and Chris were married on June 8 of 2019 during what was described as ‘an intimate ceremony’ in Montecito, CA.  

Katherine’s parents Arnold and Maria – who split in 2017 after 31-years of marriage – also share daughter Christina, 29, and sons, Patrick, 26, and Christopher, 22. 

The Terminator star has a 22-year-old son named Joseph Baena, whom he fathered with former nanny Mildred Patricia Baena, 59, while still married to Maria.
