Kaley Cuoco has filed for divorce from Ryan Sweeting citing ''irreconcilable differences''.

The 'Big Bang Theory' actress and her tennis player husband only announced their split a few days ago but Kaley is moving to dissolve the marriage as quickly as possible.

Kaley, 29 and Ryan, 28, signed a pre-nuptial agreement one month before their marriage on December 31, 2013 and she has listed their date of separation as September 3, 2015.

Kaley's net worth is approximately $45 million while Ryan is believed to be worth $2 million.

Her divorce filing states that property and spousal support information is detailed in the pre-nuptial agreement, according to TMZ.

Kaley's filing comes just after insiders claimed that Kaley and Ryan had tried to reignite the spark between them, but there was clear ''tension'' whenever they went out together recently.

A source told People magazine: ''The few times Kaley and Ryan were out together recently, the tension was noticeable. You could tell the honeymoon phase had ended.

''It seemed they were trying to work out their marriage by going on dates, but they both seemed miserable.''

Following news of the split, Kaley deleted all traces of her estranged husband on Instagram and unfollowed him across her various social media accounts.
