They were spotted leaving celebrity hotspot 1OAK hand-in-hand on Thursday evening.
And it appears 17-year-old Sofia Richie and Samir Nasri have kept their flame burning in the days that followed, as both were spotted leaving posh West Hollywood restaurant The Nice Guy within two minutes of each other on Sunday night.
The Manchester City soccer player rented out the popular venue to celebrate his 29th birthday with his rumored new girlfriend and a group of close pals.
Lionel Richie's teen daughter dressed for the occasion in an oversized chiffon sweatshirt in hues of black, bronze and creme, teaming the chic look with a black choker tied around her neck.
Sofia kept on trend with strappy suede heels in coordinating colors as well as a miniature pouch handbag.
As for her beauty routine, the younger sister of television personality Nicole Richie wore her platinum blonde waves down and around her shoulders before sweeping a light pink lip color across her pout.

The birthday boy looked handsome in an all-black ensemble consisting of a zippered bomber jacket, distressed jeans and designer sneakers.
French-born Nasri - who appeared to have a wonderful time celebrating - has been single since splitting from Victoria’s Secret model Anara Antanes last year.
Sofia, a budding model in her own right, was last linked to her longtime boyfriend Jake Andrews in April 2016.
And Richie couldn't help but celebrate her newfound flame on social media, taking to Snapchat from inside The Nice Guy to share a puckered-up selfie that featured its very own Samir-centric geofilter.
Days prior, the fledgling couple kicked off the midfielder's birthday weekend with a night of partying at 1OAK.
Sofia - who tucked a jet black camisole top into skinny jeans for the outing - intertwined her arms with Samir as they departed, but quickly retreated to the safety of her friends after being spotted.
