United Kingdom, April 11 -- Kristen Doute already has a name for her unborn baby.

The 42-year-old TV star is expecting a child with Luke Broderick, and the loved-up couple have already decided on a name for their baby girl.

Kristin told 'Extra': "She is named."

But Luke added: "We're not telling you."

Kristin recently celebrated her pregnancy with her family.

The former 'Vanderpump Rules' star shared: "I had baby shower number one back in Michigan with my family, just so wild. I'm like, 'Did I forget that I was gonna have a baby shower?'

"Like, it's so crazy to think of a baby shower, but we have another one coming up in Los Angeles that Brittany [Cartwright] is throwing for us, so we're really excited about that, too."
