Rihanna and Leonardo DiCaprio have once again sparked rumors that they’re dating. The pair, who was first linked last year, reunited at a Coachella Valley & Music Festival after-party over the weekend.

According to E! Online, the Oscar winning actor and pop star were spotted at the star-studded Neon Carnival party Saturday night. In one photo that surfaced online, DiCaprio is seen leaning in close to Rihanna as he appears to whisper something in her ear.

People magazine reports that the 28-year-old “Work” singer and DiCaprio arrived at the bash separately, but he made a beeline for her when he spotted her dancing with friends. “Leo slipped into the party incognito and was dancing and singing to ‘No Scrubs.’ A couple tables over Rihanna was dancing with a couple girlfriends. Leo saw her and made his way over to say hi,” the source said, adding that there interaction didn’t seem romantic.

The last time Rihanna and DiCaprio, 41, were spotted together was in February at a nightclub in New York. The pair also was seen hanging out at a Paris nightclub that same month.

In addition to rumors he’s dating Rihanna, the actor has also been romantically linked to Irish television presenter Laura Whitmore. According to a February report by the Sun, he invited her back to his hotel suite after meeting her at a BAFTA after-party. A source claimed Whitmore stopped by DiCaprio’s suite later that night with a group of friends.
