The Girls Aloud star was spotted leaving a branch of Starbucks before driving to a nearby recording studio.
Laden down with a frapp, orange juice and a tasty treat wrapped in a bag, Nicola made sure she was stocked up on brekkie before starting her day. Good girl!
Leaving her trademark red hair loose, Nicola was dressed casually in a black skinny jeans with zip detail, a simple tee and green jacket.
We are also loving her cute heart print trainers - and her Chanel arm candy!
Nicola has been in California for the past week and it's fair to say she is definitely working hard on new music.
But two days ago, the Liverpuddlian lass decided to take the day off to recharge her batteries.
Sharing a picture of herself on Instagram, Nicola told her followers: "I had a day off today.. It's amazing what sunlight, shopping and making your friends stay up late (because of the time difference) so you can talk to them on the phone can do for your spirit..
"I've been indoors at studio all week till it's dark out. Humans need daylight. I feel a lot better. I was almost a vampire."
Not only has she been busy writing new music for herself, Nicola has also penned songs for her fellow Girls Aloud star and BFF Cheryl Cole and Little Mix.
