Kaley Cuoco planned her shoulder surgery.

The 'Big Bang Theory' star went into hospital just five days after she tied the knot with Karl Cook but says it was her doing to have the events so close to each other.

Explaining what happened in her Instagram story, she said: ''This was a planned surgery I've had for over a year. I hurt [my shoulder] over a year ago and did not need immediate surgery so brilliantly planned it five days after our wedding. I knew I'd have a babysitter. I'm in a pretty big cast. No horsies for a minute. Time to lay low and hopefully not kill this guy [her husband]. Or him kill me.''

Kaley revealed on Thursday that she underwent shoulder surgery during her honeymoon but is ''on the road to recovery''.

She wrote on Instagram: ''When your 'honeymoon' is shoulder surgery and your husband looks just as happy lol on the road to recovery - thank you for all the love and support! knowing @mrtankcook I'm sure he will be posting tons of hilarious gems ... thank god my hair color is on point (@clarissanya) (sic)''

And as Kaley expected, her husband shared his own pictures of their ''honeymoon''.

He captioned them: ''Everyone has their own version of a newlywed glow....well @normancook yours is memorable #shouldersurgeryhoneymoon ... @normancook snoring like a distressed walrus. I love you so much but wow! #shouldersurgeryhoneymoon (sic)''

Kaley and Karl tied the knot last weekend in a ''unique'' wedding based around the couple's animals.

Wedding planner Lauren Tatum said: ''The whole [wedding] was unique and unusual, including their horseshoe altar. That was Karl's ranch. The horseshoe altar was 10 feet tall by 8 feet wide. They love their animals. The two things that were most important to Kaley were that everyone could feel the love between her and Karl, and their love for their animals. That is what they cared about - the animals and each other - and that is what they wanted relayed to the guests; that those are what is most important in both of their lives forever and always.''
