40 is the new 16, and these people are ringing in this milestone birthday with bashes bigger than a sweet 16. Bravo is bringing us into the world of wildly, extravagant fortieth birthday parties in the new reality series, "My Fab 40^th."

The posh venues, to pricey gowns, and custom cakes, these 39-year-old are turning the page in a big way.

The series of 6 episodes will celebrate the birthdays of two sorority sisters, a racecar enthusiast, a single Dad, best friends, a "conscious uncoupling" surprise, and a rags to riches entrepreneur couple.

"My Fab 40^th" premieres on Tuesday, August 25^th at 10pm ET on Bravo after the season premiere of "Below Deck."
