With the wedding and star studded reception fast approaching, Katherine has been hard at work.

But in between picking out napkins and finding a photographer, the beauty treated herself to a healthy snack at the start of the week.

The daughter of Arnold Schwarzenegger was spotted out in Los Angeles on Monday grabbing some green fuel.

Schwarzenegger dashed to her car after buying herself a juice and immunity shot to-go from Juice Crafters.

She wore a yellow sweater and jeans for her casual errand.

The snack was much needed as planning for the big day appears to be amping up. 

'The couple plans to have a star-studded event filled with family and some of the biggest celebrities in Hollywood,' said the source for ET. 

Their Hollywood friends include Bryce Dallas Howard, who worked with Chris on Jurassic World, and Whitney Port, a close pal of Katherine's.

After Chris got down on one knee at the start of the year, Katherine and her man have been hard at work preparing for their big day.

Shimmer like Katherine in a gown by Monique Lhuillier

There was so much glamour going on at the Avengers: Endgame premiere in Los Angeles recently, that we hardly know where to start!

Miley Cyrus rocked Saint Laurent, Brie Larson looked beautiful in Celine and Scarlett Johansson turned heads in metallic Versace. But there was one couple that really caught our attention.

It might have been Chris Pratt and fiancée Katherine Schwarzenegger's red carpet debut, but the bride-to-be looked like a natural in her stunning Monique Lhuillier gown. We love the one shoulder shape and almost leopard print-esque embellishment. The draped shape is super flattering and the thigh high split is a nice touch too!

With plans to walk down the aisle later this year, speculations are well underway for what all the bash will entail.

And thanks to one source for Entertainment Tonight, it looks like it's shaping up to be a very glamorous night.  

Another requirement for the party is that it's nothing short of a good time.

'Katherine and Chris want the wedding to also be fun, as the couple always has a good time together,' the source said.

As for who's been doing most of the planning, it's been revealed in the past, as well as now, that the author has taken over.

'Katherine has been in charge of most of the wedding planning as Chris had been promoting his movie, but he does give suggestions and helps when he can,' they said.

Luckily for the actor, Katherine is an avid party planner. 

'Katherine is having the best time planning everything. She loves it!' sources said previously.

While the 39-year-old actor has been busy promoting his new blockbuster Cowboy Ninja Viking, Katherine has been relying on her mother Maria Shriver to help her get things organised for their big day.

Maria, 69, said: 'Wedding planning is fun.'

She added, 'I think it's always great to celebrate love. It's the most important thing in the world. You learn unconditional love ideally from your mother and then if you find it in your life, you're blessed.'

The Jurassic World star announced on Instagram in January that he had popped the question to Katherine - who is 10 years younger than him. He shared a photograph of the brunette beauty's diamond jewel on her ring finger.

He captioned the post: '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!'

This won't be the first time Chris has tied the knot as he was previously married to Anna Faris, with whom he has six-year-old son Jack, from 2009 until 2018.

Anna and Chris finalized their divorce last year.
