Scott Disick, 37, and Sofia Richie, 21, reunited for the first time on Saturday, since ending their nearly three-year relationship in May.
The pair - who first began dating in 2017 - grabbed lunch at Nobu restaurant in Malibu, before heading to a pal's low key Fourth Of July party at the beach.
Sofia showed off her taut tummy in a color-blocked sports bra and a pair of high-waisted pants as she trekked through the sand with Scott.
They arrived to the beach in Scott's black Mercedes G-Wagon that he skillfully parked on the street.
Scott put his keys in his pocket and met Sofia on the passenger's side, so they could walk side-by-side to the oceanfront gathering.
When the couple arrived, they were greeted by friends and whisked towards a set of outdoor lounge chairs.
Scott took a seat and grabbed a beverage to sip-on, while Sofia stood over him.
After spending a decent amount of time together, Sofia grabbed a beach towel and ventured onto the beach with a female friend.
With the breeze picking up, she had a difficult time laying out her towel without it blowing back at her.
Sofia had a black cloth face mask over her mouth and nose, while the couple were dining at Nobu, but, once they reached the beach, she removed it.
Her golden blonde hair was parted down the middle and flew about in the breeze as she mingled with friends.
The daughter of Lionel Richie kept a pair of black RayBan shades over her eyes and rocked various pieces of golden jewelry on her neck, wrist, and ears.
Scott covered up his brunette locks with a black cap and had a pair of aviator shades on his face.
The Talentless founder looked beach appropriate in a navy blue tee, a pair of Prada shorts, and sneakers.
Scott and Sofia's break-up occurred in May, shortly after Scott's brief rehab stint at a Colorado treatment facility in late April.
Last month, a source told People that Sofia was 'still processing the breakup' and having a hard time doing so.
'It was a serious relationship, not some fling, and she was there for Scott through some tough times. It hurts to see all the speculation about Scott and Kourtney, but she is so young and gets so much attention. She'll be totally fine,' the insider explained.
Sofia and Scott started dating in the fall of 2017 about two years after he split with reality star Kourtney Kardashian, 41.
Recently, Scott, Kourtney, and their three children, sons Reign, five, and Mason, 10, and seven-year-old daughter Penelope, have been spending a lot of quality time together.
