Did I miss something?

When the supermodel showed up outside of the women's detention center, how did she know the cabbie would be there? I thought it was going to turn out she was there visiting some model friend who'd been busted for drugs, or some other reason justifying her presence there, but I didn't hear anything. It seemed like she was there to see the cabbie again, but then how did she know he'd be there? If she remembered his name and the cab company, I guess she could have checked with his supervisors, but that seems a stretch. I think some explanation would have been nice.
