They debuted their romance on Sunday, the very day Russell Brand’s divorce from Katy Perry was finalised.
And this morning the funnyman and his latest squeeze Isabella Brewster enjoyed a leisurely stroll.
They each sipped on coffee as they walked side by side and while Russell appeared to be playing it cool, his girlfriend was evidently hanging on his every word.
The pair showed that despite their budding relationship they are already very comfortable with each other as they both sported relaxed and dressed down ensembles.
Russell was wearing a black top and matching harem pants, along with a grey scarf, beanie hat and pair of flip flops.
Meanwhile Isabella, the younger sister of Fast & Furious star Jordana, was clad in a striped tank top, skinny jeans, two-tone ballet pumps and a white scarf.
The pair spent the morning together after revealing their romance to the world on Sunday when they took a trip to Pacific Palisades Market, where Russell happily put his arm around his girlfriend.
According to Radar Online, Isabella recently left her job as a talent agent at Creative Artists Agency.
Isabella is no stranger to the public eye and her romance with Russell Brand is not her first high-profile relationship.
Back in 2009 she dated Bradley Cooper prior to his relationship with Renee Zellweger.
The brunette then went on to date Milo Ventimiglia of Heroes fame.
