Kristen Doute has given birth to a baby girl

She told Us Weekly magazine: "She's here, and we still can't believe it. Luke is even hotter as a dad, and I just feel so lucky.

"And even though I haven't slept or showered in two days, seeing our daughter and finally being able to hold her makes it all worth it. We're completely overwhelmed with love and so grateful for her-our lives are already changed completely."

The couple chose Kaia's name, which is Hawaiian for "the sea", because of their love of the state where they got engaged.

Kristen explained: "We knew we wanted our baby name to have something to do, or revolve around, water.

"Lillies are my favourite flower. They're associated with new beginnings, beauty, and also the name Lily indicates a 'gentle and compassionate nature, suggesting a kind and caring personality.'"

Kristen admitted in April she and Luke had already chosen a name for their baby.

She told Extra: "She is named."

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

Kristen suffered a miscarriage in 2023, and she appreciated the support she's subsequently received from her fans.

She previously said: "It's been a really wonderful community of women out there who I know have really appreciated me coming out and saying that, as much as I felt really secure in coming out and talking about it because of those women.

"This is what I love about being on a reality show, a docuseries, what I love about the good things about social media, is that you are able to find these people that help rally around you, so it makes it a lot easier when you have people to talk to.

"And obviously, like, surprise! We did conceive, it worked, so that's also really exciting."

Kristen announced her pregnancy in November, revealing that they started trying for a baby at the start of 2024 and had sought the advice of a fertility specialist.

She told People magazine: "In late summer, we decided to meet with a fertility specialist to learn about our options and what could be the next step if we decided to go that route. The next month was a whirlwind - getting educated on fertility, and eventually hormone shots and preparing my body for IUI (intrauterine insemination)."
