Khloe Kardashian and James Harden celebrated his birthday earlier this week, but unfortunately, their night out as sea quickly turned sour.

According to a report on Wednesday, the Keeping Up With The Kardashians star and her rumored NBA boyfriend enjoyed a yacht party for Harden's 26th birthday, and while out on the ocean, they lit up the sky with a 15-minute firework display, which residents of the nearby towns weren't happy about.

"Khloe Kardashian and James Harden threw their own personal 4th of July with a GIANT fireworks display that woke up thousands of residents -- and city officials are scrambling to find out HOW it got approved," TMZ reported. "The thunderous fireworks show -- visible from multiple towns along the oceanfront -- went on for 15 minutes at the stroke of midnight."

The report claimed city officials were confused by who would have allowed such a display to happen on a Tuesday night, and at the time the report was initially published, the issue remained a mystery. However, hours later, TMZ offered an update.

"We've now learned Khloe and James did NOT need a permit to set off the fireworks," the site explained. "They did need the Coast Guard to sign off on the safety of the display, and they got that."

Kardashian has been linked to Harden since earlier this summer, following her breakup from rapper French Montana.
