A source said at the time: "Leighton and Adam got married in Northern California by the ocean a couple of weeks ago. It was a very small and intimate wedding with close family and friends. It was beautiful."
The 29-year-old star first hinted she and her 35-year-old beau were trying for a baby during a recent magazine interview.
She said: "Most people I know are starting to get married. It'll be kids next. I like the grown-up stuff. I like having a house. I've got dogs.
"I started [Gossip Girl] when I was so young. And once it was over, I wanted to do things that were exciting and challenging and more me - more my adult taste."
Meanwhile, Adam previously joked he is hoping to have a very big family with Leighton.
Asked how many children they were planning on having, he said: "I say twelve. And I decide."
