Bravo at the Derby. Tonight!

What's a sire? Which horse is a filly? Do you have a stud book handy? Forget all of those pesky horse racing terms and have some Kentucky Derby fun.

Tune in TONIGHT at 5 ET/PT for "Ladies First: Bravo at the Kentucky Derby."

Join one of our fave Housewives and horseracing afficianado Bethenny Frankel as she breaks down the action on the racetrack and all the crazy Derby fashion (those hats!) with "Access Hollywood" co-host Nancy O'Dell. Also teaming up with the ladies (for you sports nuts out there) will be NBC's own Bob Costas.

"Top Chef: The Tour" will be stopping by so stay tuned for chef'testants Hosea, Stefan, and Stephanie as they set up shop and get cookin.'

Wait! It's not just about food and fun, there's a good cause involved too. Kentucky Oaks 135,  the Derby's companion event, will feature a day of events, including a First Lady of Fashion Contest, to raise money for breast cancer organization Susan G. Komen for the Cure®. "Ladies First" will be airing the festivities.

So whether you're a sports fan, a food fan, or just a Bethenny fan, there's sure to be something for you. Catch all the fun while sippin' on one of Bethenny's Skinnygirl Derby cocktails. Get the recipes HERE.

And get some Derby fashion inspiration by checking out the Housewives in theirmost stylin' (and outrageous) hats!
