Speaking to Now, the former Pussycat Dolls singer said that she wants to be married before having children with the Formula One star.
She said: "I'm really traditional - I'd want to be married before we have kids and that's something we'll hopefully be doing soon.
"I love kids and I'm feeling broody. Lewis is always telling me that I'd be a really good mum and I know he'd be a great dad."
The 32-year-old added: "He's really sweet - he'll fly halfway across the world to see me perform for just one night, then fly back again to where he needs to be."
Scherzinger recently appeared as a guest judge on The X Factor, and is reportedly in line for a role on the US version of the show.
