Anyone who opened a tabloid in 2013 will attest to the fact that the marriage looked wonderful on paper.

Tennis ace Ryan Sweeting proposed to Kaley Cuoco, star of The Big Bang Theory, in September 2013 with a 2.5-carat diamond engagement ring costing $65,000.

What happened to Kaley Cuoco and Ryan Sweeting?

The couple married on New Year’s Eve 2013 at the Hummingbird Nest Ranch in Santa Susana, California, in a widely publicized wedding. Cuoco arrived wearing a custom-made pink Vera Wang wedding gown with a sweetheart neckline and hand-appliqué Chantilly lace details.

The wedding cake was designed to resemble an upside-down chandelier. They had just been dating for six months.

Unfortunately, the “Fire and Ice” motif of the wedding turned out to be tragically appropriate. The “Big Bang bombshell” was out of the bag by September 2015: the pair was splitting after only 21 months of marriage.

Why did they divorce?

Cuoco filed for divorce, alleging irreconcilable differences, according to court documents acquired by PEOPLE at the time.
