Lady GaGa feared she'd be alone forever.

The 'Joker: Folie a Deux' actress got engaged to Michael Polansky in April after five years together but the 38-year-old star - who was previously engaged to both Taylor Kinney and Christian Carino - admitted she had been worried she'd never find the right partner.

She told America's Vogue magazine: "I kind of thought I was going to have to do this all by myself—forever. And that was really scary. Because it’s a big life. And I don’t think anyone really knows what it feels like unless you’re in it.

“And I don’t have to do this alone anymore.”

The 'Bad Romance' hitmaker was introduced to Michael through her mother, Cynthia Germanotta.

She recalled: “My mom met him and she said to me, ‘I think I just met your husband,’ and I said, ‘I’m not ready to meet my husband!’ I could never have imagined that my mom…found the most perfect person for me?”

Gaga and Michael finally met at the 40th birthday party of Facebook founding president Sean Parker and hit it off immediately.

She recalled: "I got invited and I said, ‘I wonder if Michael is going to be there,’ and my mom said yes, and so I went to the ​party and I kept asking for him and he finally came over to me and we talked for three hours. We had the most amazing conversation.”

Michael added: “I didn’t know much about her and honestly wasn’t sure what to expect. I was struck immediately by her warmth and openness—she was so genuinely curious about what my life was like growing up in Minnesota.”

They talked on the phone for weeks and then "just fell in love" on their first date before the COVID-19 pandemic hit.

While Michael had been living in San Francisco, he moved to quarantine with the star in Malibu and they are grateful to have had the "gift" of quality time together.

Gaga said: "It was really kind of special. I’d been so focused on my career since I was a teenager. And the gift of that time was that I got to completely focus on my relationship. I met this totally supportive, loving human being who wanted to get to know me—outside of Lady Gaga...

“It was very painful to see how deeply [the pandemic] affected the world.

"Not only how sick people got, so many people died, but also so many people were alone. I feel very grateful that I wasn’t alone. I had never met anyone like Michael. He’s so smart and so kind. And his life and my life are very different. He’s a very private guy and he’s not with me for any other reason than that we are right for each other."

Michael added: “We had this amazing chapter of a weird kind of normalcy that’s essential for any relationship to develop in a real way—taking walks, making coffee, hanging out with the dogs, reading books together.

“The pandemic was easier on her than you might think. She’s used to being isolated because of her fame and was able to take so much of it in stride. I think she loved the chance to slow down. She’s been operating at an unfathomable level of intensity for years and it’s no secret it had caught up to her.”
