It was a fantasstic evening in NYC -- as curvaceous tennis pro Serena Williams and petite Victoria's Secret model Selita Ebanks showed off their bangin' behinds.


In hindsight, we have just one question ...

You'd think she'd be a Bitter Betty about her former fiancé marrying a bigger star and giving her a blingier ring -- but Selita Ebanks is really good at hiding her true feelings.

Even though her engagement to Nick Cannon is off, supermodel Selita Banks won't have to worry about being bling-free anytime soon! Who needs a 15 carat engagement ring anyway?!

The 24-year-old beauty, seen here wearing the ring Cannon designed, sparkles in 9,000 diamonds, rubies, emeralds and sapphires on her blinged out Victoria's Secret Christmas lingerie set. Ho, ho, ho!

Is it just us or does that look extremely uncomfortable?! Ouch!

Nick Cannon is dating a Victoria's Secret supermodel, but they didn't have a secret wedding.

Rumors spread last week that Cannon and stunner Selita Ebanks got married in a quickie ceremony during All-Star weekend in Las Vegas -- after dating for only three weeks. While nobody was talking at the time, Ebanks has finally come forward to deny that they walked down the aisle.

"It's so funny, because I've been saying 'Thank you, thank you' all week -- but no I'm not married," Ebanks told TMZ at a Victoria's Secret event in New York today.

And that rock she's rockin' -- she bought it herself!
