It surely seemed like they were more than just friends at Coachella earlier this month -- Katy Perry and Diplo were recently spotted together again on their romantic dinner date.

The "Dark Horse" singer and the Los Angeles-based DJ, who have been friends for years, were "hanging out pretty much the whole night" at the Jeremy Scott and Adidas party in Palm Springs during Coachella. "It definitely looked like more than [friendship]," a source said. "At one point, he even had his arms around her." The source also revealed that Perry reacted in anger by having a female, who tried to flirt with Diplo, thrown out of the party.

On Thursday night, the 29-year-old singer and her new love interest were enjoying dinner inside the Marlton Hotel in New York City before arriving at the after-party for the "Amazing Spider-Man 2" premiere, which took place at the Skylight at Moynihan Station.

Other sources claimed that the couple spent an hour at the venue before partying at nightclub Up and Down, while Leonardo DiCaprio was allegedly there as well. While Perry tried to impress the DJ in a high-waist floral paisley print satin skirt and a black sleeveless crop top with matching platform sandals, Diplo went for more casual look in a white Kenzo tiger sweater and jeans with a pair of boots.

Although the pair made their entrances and exits separately to avoid being photographed together, they were seen traveling in the same car. At the end of their wild night, Katy Perry and Diplo allegedly headed to the same hotel.
