Paris layered a black top underneath a fitted blazer.  

The blonde stunner added a pair of color-block pants and tucked them into lace-up, mid-calf boots.

Paris completed her look with a wide, butterfly choker, oversize shades, diamond earrings, fingerless gloves and a bag from her own line.

Joining Paris for her outing was actor boyfriend Chris.

The duo came out as a couple in February, when the Stars Are Blind songstress shared a photo of themselves to Instagram.

In a previous interview with Us Weekly, the fashion brand owner spoke of their first date, and how she appreciates their alone time.  

'He came over to my house. We stayed up all night talking and getting to know each other. When we had our first kiss, I felt that electric feeling and I knew there was something special about him,' she began. 

'My favorite thing to do is to be at home with him. He is my best friend and we always have the most amazing time together. For work, I have to be out and be social all the time. So in my private time, I would much rather be at home in bed watching TV with my boyfriend and puppies than out at a club.'

In a chat with Time magazine, the businesswoman confessed that she's ready for the next step in her life, parenthood. 

'I can't wait for the next step in our life, to have beautiful babies,'  she began. 

'Then I feel like my life will be complete, you know what I mean? I may feel like a kid and look like a kid, but I'm not. I would love to just, like, move on. To continue being a businesswoman, but to have a family.'
