Leonardo DiCaprio & Miranda Kerr Party in N.Y.C. with Cameron Diaz

Wednesday December 05, 2012 12:25 PM EST

Miranda Kerr and longtime pal Leonardo DiCaprio joined a late-night dance party at new club Rosewood last Friday, partying with Cameron Diaz and a contingent of Australian models.

Their meet-up at the club comes amid some tabloid reports that Victoria's Secret model Kerr – who's married to Orlando Bloom, 35, and gave birth to their son Flynn in 2011 – was getting flirty with DiCaprio.

But a club source at Rosewood said the two were simply out for a little music and dancing with a group that included Naomi Campbell's billionaire boyfriend Vladimir Doronin.

"Miranda and Leo are really good friends, been friends for years," the source says "It was a PG -13 fun night. ... It was one big table [of people] ... dancing on top of the banquette."

Adds a source close to the Victoria's Secret model: "Miranda is visiting Orlando this weekend in London, and all the rumors about them having trouble are much ado about nothing." (Bloom has been in South Africa shooting his latest film Zulu, according to reports.)

Kerr, 29, and DiCaprio have been spotted around town together – at The Darby on Nov. 10 for a birthday bash for DiCaprio, dining with a group at ABC Kitchen on Nov. 21 and, most recently, at Rosewood last Friday.

DiCaprio, who turned 38, recently split with model girlfriend Erin Heatherton.

Meanwhile, a second source calls any talk of a romance between DiCaprio and Kerr "B.S," adding, "They are just friends."
