E! News has learned the "Roar" singer enjoyed a dinner with the famous DJ at celebrity hotspot Andrea's inside Encore at Wynn Las Vegas Monday night.
The cozy pair was part of a group of 14 celebrating a friend's birthday. During the evening outing, Perry and friends enjoyed a Wagyu beef tasting, an assortment of sushi, ice cream and even a flaming Mt. Fuji dessert.
But in true Vegas fashion, dinner was only the beginning of this fun night out.
Perry and her close friends later headed to XS nightclub where they waited for Diplo to take over the DJ booth. As soon as he took control, the group sipped cocktails and danced the night away.
Rumors of a romantic relationship between Diplo and Perry first sparked after the two were seen getting flirty at a Coachella Music Festival after-party in April. They would later enjoy a romantic getaway to Jamaica in June.
But despite spending quality time together, sources tell E! News the pair are not dating and simply just friends.
