I met billionaire Topher Brodie in the most graceful way -- by crashing my airport shuttle into his limo. He didn’t take it well. Actually, he got me fired.

The only upside? I figured I’d never see him again.

So imagine my shock when I overheard him introducing me as his girlfriend. His what now?

Turns out, Topher’s mom is sick, and to keep her life stress-free, he invented a relationship . . . with me, Kathleen Avery.

Frankly, I’m shocked that anyone believes that we’re a couple. He’s a workaholic in a thousand-dollar suit with a private plane, a yacht, and several vacation homes, and he usually dates supermodels. And me? Well, I'm not a supermodel, and my net worth couldn't cover his dry-cleaning bill.

It was only supposed to last a few weeks. Just long enough to help him out and get a warm place to crash in return. No feelings, no strings, just one absurd lie.

But the longer I play along, the harder it gets to remember what’s fake. And what’s not.
