Lady GaGa is "so excited" to start a family with her fiance Michael Polansky.

The 'Poker Face' star got engaged to Michael in April after five years together and they are now planning their life together with the singer admitting becoming a mum is "number one" on her list of life goals.

When asked about her plans for the next 15 years, Gaga told BuzzFeed Canada: "I’m so happy to be in love, and I’m so excited to have a family. So that’s definitely number one."

She went on to insist she's keen to continue growing and relishes the challenge of keeping up her pop career as she gets older.

Gaga added: "I really believe in the ability to grow as a person and I think that feeling can give everybody hope and I just want to keep growing and also I'm 38 years old and it's kind of fun to embrace the challenge of being a 38-year-old pop star and figuring out who I want to be now.

"And what I want to say because I really love women and I really want to be a voice that deseres to be a part of our community."

It comes after the singer - who was previously engaged to both Taylor Kinney and Christian Carino - admitted she had been worried she'd never find the right partner before meeting Michael at a pal's birthday party.

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."

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."
