Kaley Cuoco recently stirred up a storm on social media by announcing that she and Ryan Sweeting are getting a divorce after 21 months of marriage. The news, however, did not take anyone by surprise, as rumours about their marriage troubles started swirling soon after their surprise wedding in 2013 on New Year’s eve.

The break-up was announced on Sept. 25, and according to reports, the couple was already separated as early as Sept. 03. The 29 year-old “The Big Bang Theory” star has reportedly filed for divorce citing “irreconcilable differences.”

Prior to the announcement confirming the divorce, tabloids continued to hint at Cuoco and Sweeting’s crumbling marriage, though the two were often seen together and all over each other.

Cuoco and Sweeting’s story is a perfect example of a whirlwind romance that bites the dust after reaching the altar. The couple met, got engaged, got married and divorced in a span of two years. The actress got engaged to the professional tennis star after dating him for three months, and the wedding soon followed. Now, it is a quick divorce.

Now that the actress is single again, let’s take a look back at the blond beauty’s previous romances:

2004 – Kevin Zegers

Rumours of romance between the Canadian actor and Cuoco sparked when they starred together in “The Hollow.”

2006 – Jaron Lowenstein

Country pop singer Jaron Lowenstein, former member of the musical pop duo Evan and Jaron, publically dated the actress, but it was a brief romance that did not last for long.
