The 'Big Bang Theory' star posted about the emotional nuptials between his on-screen partner - and real life former flame - in a touching social media post following their special day on Saturday (30.06.18).
He wrote: ''Couldn't be happier for my fake wife @normancook and @mrtankcook whose words brought us all to tears last night. So much love for you both.''
Kaley wed the professional equestrian in a romantic ceremony in San Diego, Southern California, and confirmed it alongside a moving black and white snap.
She captioned it: ''Legally KCSQUARED 6-30-18.''
Kaley, 32, opted for a flowing lace gown and wore her blonde hair tied back in a low bun.
She later changed into a white jumpsuit for the evening festivities.
Kaley has previously called Karl her ''soulmate'' and said they could not wait to tie the knot.
She gushed: We're totally going to get married. We are planning it. We are thinking about it. I can't wait. I don't want it to be much longer. That's the truth. I really can't wait.
''We are so happy and in love. He is excited as I am, which is sweet. I finally found my soulmate, so we're ready to do it.''
The actress was previously married to former tennis player Ryan Sweeting but said that their divorce had originally made her believe she would not wed again.
She said: ''I honestly thought I wouldn't get married again. My ex ruined that word for me. I married someone the first time who completely changed. The person I ended up with was not the person I originally met. And that wasn't my fault - that was his. I knew how much I had to give and how much I wanted to receive. I knew I just had to be patient ... I had to go through a lot of things, but it brought me to Karl.''
