Did Miranda Kerr just have a secret rendezvous with billionaire Steve Bing? She most certainly did!

Over the weekend, our photogs followed Orlando Bloom's ex from her home to the what turned out to be Steve Bing's Malibu home -- and when the two saw that they were being photographed tried to hide. These two were putting in a lot of effort to keep their meet up a secret -- maybe that's because Kerr has been dating media mogul James Packer and didn't want to be seen?!

Our photog on the scene said that Kerr was acting all sorts of nervous, "She was definitely sneaking around. She was driven there, and was hiding in the passenger seat of her car the whole ride and then tried to hide when she got out of her car. Once Steve Bing saw us, he acted really nervous and made an effort not to be seen with her. These two definitely didn't want to be photographed together."

This secretive meetup doesn't seem like the behavior of two people who are "just friends"! It's possible that Kerr and Packer have parted ways -- but why else would the supermodel being hiding?

We think the whole thing seems pretty suspect. Kerr has been dating Packer, who is richest person in Australia and has an estimated net worth of $7.9 billion, for a number of months. But on Saturday, joined playboy Leonardo DiCaprio and a bunch of scantily clad women at Nobu in Malibu. After enjoying a Halloween-themed dinner at the trendy eatery, the crew climbed into DiCaprio and Packer's car and continued their night at Hollywood nightclub, Blue Collar. We don't know about Miranda, but we definitely wouldn't want our man hanging around those girls!

Whatever's going on with this bizarre billionaire love triangle -- we know one thing: Miranda Kerr's got a very rich man waiting in the wings for her!
