Kaley Cuoco, 29, and Ryan Sweeting, 28, are divorcing.

The news broke late Friday that The Big Bang Theory star and tennis player decided to part after 21 months of marriage. Cuoco's rep, Melissa Kates, confirms the split to USA TODAY.

According to People, the couple mutually decided to end their marriage.

The couple married in December 2013, just three months after they began dating, and were known for often striking sweet poses on red carpets. Cuoco has often shared shots of the pair on Instagram.

In April, Cuoco fought back against rumors of an imminent split. "I have never been more proud of anyone on this planet – this guy is fighting back from a whirlwind of injuries and not to mention constant 'conversation' regarding our marriage and basically any daily decision we decide to make," she wrote on Instagram.

Both made moves to get ahead of the announcement. Us Weekly notes that prior to the news dropping, Cuoco deleted most shots of Sweeting from her social media accounts, and Sweeting stripped his Instagram account clean and disabled his Facebook page.
