American actor/film producer Leonardo DiCaprio reportedly got close with Fifty Shades of Grey actress Dakota Johnson during the Saturday Night Live 40th anniversary after-party held at The Plaza Hotel in New York city.

According to Life & Style, the Titanic star paid no attention to rumoured girlfriend Rihanna, who was also in attendance.

An insider revealed: "He put his arm around Dakota and led her into the grand ballroom. He told her, 'Let's go look at all the celebrities'."

"Dakota looked like she was trying to play it cool, but you could tell she was thrilled to have his attention. Out of everyone he socialized with, Leo seemed to be the happiest when he was with Dakota," the source went on. "As they walked away, Leo took the lead and guided her through the crowd, and a small smile spread across her face."

Rumours that Chris Brown's former girlfriend and DiCaprio are dating, started last month and apparently, the two have been spending a lot of time together.

During an interview with Elle, Rihanna revealed her words to live by.

"'Avoid obviousness.' That is a quote by Leonardo DiCaprio. That's what makes you create something, that's the excitement, that's the thrill," she said.

It was previously reported that Rihanna and DiCaprio spent Valentine's Day together.

Adding on, the 40-year-old Wolf Of Wall Street star also helped to organise her 27th birthday on 20 February.
