Country songstress Miley Cyrus says she feels "most confident" about her relationship with actor Liam Hemsworth, and has gushed about how "hot" her beau is.

The singer is engaged to the 'The Hunger Games' star Hemsworth, and has opened up about her romance in the new issue of Cosmopolitan magazine.

Speaking to the publication, the 20-year-old star revealed: "Number one is my relationship with Liam. That's what I feel the most confident in because you never know; there's so much hype behind my new record, but it could come out and, worst-case scenario, everyone f***ing hates it."

Cyrus also gushed about how attractive her husband-to-be is.

She giggled: "I'll literally look at him and be like 'You are hot, dear god!' The other day, I turned on the pool heater and it was steaming, and he walked outside and took off his clothes and jumped in the pool."
