Leonardo DiCaprio 'hooking up' with Miranda Kerr, cheating on Toni Garrn? Orlando Bloom's sexy ex now actor's new Victoria's Secret Angel?

Leonardo DiCaprio and his Victoria's Secret sweetheart Toni Garrn were spotted kissing at Kanye West's NYC concert on Sunday (Nov. 24). So... why is Star magazine reporting that DiCaprio dumped Garrn and is now hooking-up with gorgeous model Miranda Kerr?

Back in October, Kerr and her husband Orlando Bloom officially announced their separation. Initial rumors suggested that the 30-year-old Australian beauty was flirting with Justin Bieber, and Bloom got really ticked-off:

But now Kerr has supposedly moved-on again... with 39-year-old Hollywood heartthrob, Leonardo DiCaprio.

According to the seedy gossip tabloid, Kerr and DiCaprio "were spotted dining at SushiSamba in the Palazzo Hotel in Las Vegas on November 17." An alleged insider reveals, "He's been after her for a long time... Now that she's single, he's going in for the kill... Leo and Miranda have always been insanely attracted to each other."

The popular Hollywood bachelor is known for romancing stunning Victoria's Secret Angels - he's currently dating 21-year-old German model Toni Garrn:

The couple got "affectionate" at Yeezy's concert at Madison Square Garden over the weekend:

Gossip Cop spoke with a legit source close to the actor, who insists that such rumors are "100 percent false." DiCaprio has yet to move-on from his romance with Garrn... yet.
