"Big Bang Theory" star Kaley Cuoco-Sweeting opens up about her social media addiction and the men in her life, including new husband Ryan Sweeting.

The 27-year-old actress, who is the cover girl for the May issue of Cosmopolitan Magazine, managed to keep her two-year relationship with co-star Johnny Galecki a secret until the former couple decided to go their separate ways.

But before marrying her tennis player husband, Cuoco-Sweeting had a 10-day fling with "Man of Steel" star Henry Cavill.

"I had no one following me until I met Superman," she told Cosmopolitan. "I've been in this business for 20 years, and my whole life, I could go anywhere, do anything. There had not been one paparazzi photo of me until like several months ago. The recognition was crazy."

The couple ended their relationship last summer and the actress quickly moved on to Sweeting. The duo got engaged after three months of dating and married on New Year's Eve.

"I admit it happened fast, but that's who I am," Cuoco-Sweeting said. "When we met, I knew he was the one. [At my wedding], I felt like a rock star and a badass. What was amazing in that room, it was so full of love. It was like nothing I'd ever been to before, and it was exactly what we wanted it to be. It was the eighth wonder of the world, the greatest wedding of all time."

Cuoco-Sweeting told the magazine that she still holds her friendship with Galecki close to her heart, despite there being a "bit of awkwardness," while filming together post-split. She said the two eventually became "best buddies and moved on in such an elegant way."

"(He's) one of my closest friends," she said. "He was in the front row at my wedding with a huge smile on his face."

The actress also admitted to the magazine that she cares what people have to say about her.

"I started reading [the social media comments] and thought, 'Maybe I need to make more of an effort and not go out in my UGGs and be disgusting,'" she told the magazine. "So I started putting on makeup. And they started writing, 'Wow, someone really likes being in front of the camera' and 'Her hair's done now for coffee.' I couldn't do anything right."
