The lovebirds stepped out as a couple for multiple art events in Miami Beach, Florida, this week, seemingly playing it up for the photographers who were snapping their pics.

On Wednesday, Disick, 34, and Richie, 19, coordinated ensembles for DuJour's Jason Binn And WellNEST Celebrate Miami Beach's Art Basel Kick-Off at The Confidante. The blond beauty wore a chic black mini dress with strappy heels, while her beau sported black slacks, matching shoes and a dress shirt that he buttoned halfway.

Disick and Richie looked equally stylish on Thursday while attending an art exhibition by Alec Monopoly and David Yarrow. For this soiree, the model opted for a more casual ensemble, which consisted of a black tank top and high-waisted pants. Disick donned a pair of light wash skinnies and a striped shirt, placing his arms around his girlfriend and Monopoly for a snap inside the pop-up, presented by Haute Living

So sweet!

Back in October, a source told ET that Disick and Richie were "still going strong" and "having a great time" together. According to the source, it’s unclear how "serious" their relationship is, but they're "happy and having fun for now."
