Halle Berry and Alex Da Kid's relationship is going strong.

On Tuesday, Berry, 51, and Da Kid, 35, attended Treats! Magazine's 7th Annual Halloween Party together at the Mayan in downtown Los Angeles. The pair arrived at the event in a new Rolls-Royce Black Badge. They dressed up as mummies, wrapping white tape around their faces and hands, Us Weekly reported.

"They had a table near the DJ," a source told the publication. "They stayed for over an hour at a table by the stage. They kept to themselves and stayed close together. They seemed like they were having a nice time. The three mummies stayed close – the third was a friend – Halle and Alex seemed particularly close. They were laughing intimately at the table."

Aside from the pair, Gerard Butler, Paris Hilton and Chris Zylka, Josh Hutcheson, Diplo, Scott Eastwood, Chanel West Coast and Logan Paul were also spotted at the event. They danced to the beat created by DJ Black Coffee and enjoyed cocktails by Absolut Elyx and Perrier Jouet.

Meanwhile, the "Extant" star confirmed her romance with the British music producer in September when she shared a photo of them together on Instagram. In the snap, Da Kid is hugging Berry from behind. "My balance," she wrote in the caption.

After Berry made her relationship with Da Kid Instagram official, a source revealed that the two have been seeing each other for a few months already. They met through their mutual friends in the industry.

Berry has gone through three failed marriages. She was previously married to David Justice (1992 to 1997), R&B singer Eric Benet (2001 to 2005) and French star Olivier Martinez (2013 to 2016). Earlier this year, the "Monster's Ball" actress shared the lessons she learned from her relationships that didn't work out.

"I have learned to deal with three failed marriages, which has not been easy, especially when there's children involved," Berry said (via Us Weekly). "[As] women, we go into marriage thinking it's going to last forever and that this is our prince on a shiny horse. That's what fairy tales taught me as a kid ... and I'm kind of anti-fairy tales today."

"We all come here with lessons that we have to learn, and those relationships provided me with lessons that got me to where I am right now. For that, I'm grateful. But it has been hard. It's been a difficult part of my life," Berry added.
