Miss Universe Riyo Mori and Miss USA Rachel Smith arrive at Planet Hollywood Resort & Casino’s grand opening in Las Vegas.

Where’s Miss Teen USA, Hilary Cruz?

I’m guessing she couldn’t come because she’s not 21.

She’s probably back in NYC, not getting into any trouble at all …

Heh.

Miss Universe Riyo Mori, Miss Teen USA Hilary Cruz and Miss USA Rachel Smith attend A Salute to the Troops in NYC.

Check out Riyo, still rocking that bling from the night before.

Rumor has it that Nick Cannon — who recently split from model Selita Ebanks — has his eyes set on the reigning Miss USA, Rachel Smith.

“Last week, he sent her several dozen roses, chocolates and balloons,” said a source. “When she opened her apartment door, the hallway was flooded with stuff, and on each item was a different hand-written note from Nick to her.”

The two haven’t actually been on a date yet.

This sounds like something a publicist planted. I just wonder whose publicist.
