Leonardo DiCaprio and Rihanna have once again fuelled dating rumors after they were spotted together at an opening of a Las Vegas nightclub over the weekend. The two were seen reuniting at Coachella last month after several reports romantically linked them.

Rihanna, who was in Las Vegas for her Anti World Tour, decided to make a surprise entry at the grand opening of Intrigue Nightclub at Wynn Las Vegas casino hotel, Entertainment Tonight reported, citing a witness. The “Diamonds” singer walked to the VIP section of the nightclub, where she was seen having a chat with DiCaprio.

The source told Entertainment Tonight that the two were “whispering into each other’s ears.” Later, the two left separately with their friends, the report added.

DiCaprio has been linked with several stars — mostly with Rihanna — after his breakup with model Kelly Rohrbach sometime last year. DiCaprio and Rihanna were also spotted getting cozy at a Coachella Valley & Music Festival after-party earlier this month. In a photo that surfaced online, DiCaprio is seen leaning in close to Rihanna as he appears to whisper something in her ear.

Last month, the 41-year-old Oscar Award winner who has been linked with several celebrities lately, went on a dinner date with 24-year-old model Roxy Horner in New York City. This set off speculation that Horner and DiCaprio might be dating.

On Sunday, an Inquistr report’s headline said Rihanna — who previously dated Chris Brown and rapper Drake — may be in “direct competition for Leonardo DiCaprio’s heart with this blonde bombshell,” referring to Horner.

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