The model, 28, wore a tight, black minidress paired with a leather jacket and ankle boots for the night out, while Andre mirrored her edgy look in a leather jacket with ripped black jeans.
Andre, 24, is a well-known EDM producer and is part of the electronic duo DVBBS alongside his brother Chris Chronicles. The two shot to fame in 2013 with their hit "Tsunami."
"There were no specific signs of PDA but they were lightly holding hands at the dinner table," an onlooker tells PEOPLE of the couple, who stayed at ROKU Sunset for over an hour.

According to the source, the duo sipped on Pacific Scorpions and sake while digging into diced yellowtail, shishitos and salmon sashimi.
The outing comes after Efron removed all photos of Miró from his social media accounts and stopped following her on both Instagram and Twitter.
Efron and Miró began dating in 2014 but PEOPLE confirmed that the pair called it quits just months ahead of their two-year anniversary.

The sudden split came just two weeks after the former couple were spotted food shopping together at an L.A. supermarket. The two were also seen looking happy in love at the MTV Movie awards on April 10.
"A month ago he was talking about how he missed her when he was away shooting Baywatch," a source tells PEOPLE of Efron, who, the source adds, would come home on weekends to see Miró.
Miró later attended Coachella without Efron over the weekend, where she was seen hitting up the Nylon, Calvin Klein and Jeremy Scott parties.
