Disick, 35, and Richie, 20, celebrated their second romantic holiday as a couple together with a date night at the Theater Box Entertainment Complex in San Diego.
The two enjoyed an early screening of the new film Isn’t It Romantic while snacking on candy and popcorn.
They were also treated to a giant heart-shaped cake that read “Be Mine” across the top, surrounded by cupcakes and sparklers.
Ahead of the night out, Richie showed off her new Valentine’s Day gift from Disick: a pink, quilted Chanel bag.
“New lady,” she captioned a video clip showing off the bag on her Instagram Stories.
The couple seem to be going strong as they approach their two-year anniversary.
In late December, Disick and Richie went on a tropical getaway in Cabo San Lucas, Mexico with his ex Kourtney Kardashian. The reality star and Disick’s three kids — Mason, 9, Penelope, 6, and Reign, 4 — were also on the trip.
Disick had a sense of humor about traveling abroad with both his girlfriend and ex: “What more can a guy ask for. THREE’S COMPANY,” Disick captioned an Instagram image of himself relaxing on a recliner — with Kardashian and Richie sitting beside him.
A week later, the trio was spotted stepping out in Aspen, Colorado.
A source told PEOPLE that as her relationship with Disick grows stronger, Richie is continuing to navigate the complicated family dynamic.
“She loves Scott and wants to be with him,” the source said. “She loves being around Scott and his kids.”
The insider also said Richie is happy to have built up some trust with Kardashian and “proved to Kourtney that she is great with her kids.”
