She is expecting her first child with Chris Pratt some time this summer.

The 30-year-old beauty was twinning with the grandma-to-be in uplifting and powerful sweaters. 

Mom-to-be: Katherine Schwarzenegger hid her burgeoning baby bump underneath a statement white sweater on Sunday during a walk in Los Angeles 

The pair’s $169 Annie Bing sweaters read: ‘I am powerful, kind, confident, beautiful, strong, capable, grateful, I am me.’ 

Katherine hid her burgeoning bump underneath the white top and teamed the look with a pair of black activewear tights. 

She accessorised with a cap and shades and at one point was seen wearing a protective mask, amid the COVID-19 outbreak.

Maria sported the same look but opted for a white colored cap to shield her face. 

The pair were joined by Patrick Schwarzenegger, 26, and his girlfriend, Abbey Champion, for the walk. 

The family appearance comes after dad, Arnold Schwarzenegger, shared his excitement over his first grandchild last week while speaking with Jimmy Fallon.

‘I mean, that is really exciting news that Katherine now, you know [to] be pregnant and have a baby—I don’t know when exactly. Sometime this summer,’ he dished.

Katherine and Chris began dating in 2018 and announced their engagement in January 2019.

They went on to marry in April 2019 and are said to be ‘getting more excited every day’ and ‘have been adding items to a baby registry,’ according to a People source.

This will be the actor’s second time as a father.

The Avengers star is already dad to seven-year-old son Jack, who he shares with ex Anna Faris.
