These twin flames were white hot this Fourth of July holiday.

The Transformers actress, 38, wore a white Summer Crush mini dress with cap sleeves by White Fox and a silver choker while the musician, 34, sported a white T-shirt, matching pants, suspenders and sunglasses.

MGK joked on Instagram, alongside pics from the party, "I wore white to celebrate my virginity."

He and Megan, who have been dating on and off for more than four years, were joined at the bash by fellow celebs such as Drake, Tom Brady, Rob Gronkowski, Kim Kardashian, Khloe Kardashian and Megan Thee Stallion.

Megan and MGK's appearance at the party comes more than a week after they were spotted at the Nemacolin luxury resort's summer solstice celebration in Pennsylvania, another star-studded affair. The two had also coordinated their outfits for that event, with both dressed in blue-and-white pinstripe blazers.

The former President of the United States reflected on the importance of the holiday and democracy.

"The Fourth of July is about celebrating the big, bold, inclusive experiment that is our American democracy," he wrote. "And it has always been an experiment. Our democracy has never been guaranteed, which means we can’t take it for granted. We need to keep fighting for it, keep improving it, and keep making sure it reflects the better angels of our nature instead of the worst. That, more than anything, is what America is all about.

Kelly shared a series of Fourth of July photos, which included some throwbacks from her childhood. She wrote with an American flag emoji, "Fourth of July, a few snaps of celebrations from 1973-2024."

The two have not confirmed the status of their relationship since Megan revealed in March that she and MGK had, at one point, called off their two-year engagement.

"What I've learned from being in this relationship is that it's not for public consumption," she said on the Call Her Daddy podcast. "So I think as of now, I don't have a comment on like the status of the relationship."

She added, "What I can say is, that is what I refer to as being my 'twin soul', and there will always be a tether to him no matter what."
