Sorry, haters, but Cynthia Bailey is definitely getting the last laugh when it comes to her personal life. After she married Peter Thomas beneath the skeleton of a dinosaur on the Real Housewives of Atlanta, skeptical fans said it wouldn't last a year, but the former supermodel is celebrating her third anniversary this week!

Cynthia went on Twitter to gush about the milestone.

"Thank u @PeterThomasRHOA for the beautiful flowers! Today is our 3 year wedding anniversary!" the happy wife and mother wrote.

Congratulations, you two!

The couple is so proud of their union that they even wrote a book to help others conquer obstacles and achieve bliss, titled Carry On Baggage: Our Nonstop Flight.
