United Kingdom, Oct. 17 -- Olivia Culpo has suffered a "little bit of an identity crisis" since giving birth.

The 33-year-old model and her husband Christian McCaffrey welcomed their daughter Colette into the world in July, and Olivia has admitted to battling self-doubts over recent months.

Speaking on The Squeeze podcast, Olivia shared: "There's totally a shift.

"Whether or not you want there to be or not, you have somebody that's physically dependent on you. So, I'm not going to sugarcoat it: Yeah, it's scary."

Olivia has been career-focused for many years, and she worries how she'll balance motherhood and her modelling career.

She said: "I'm just kind of a worry wart that way, like I'm very ambitious."
