Hailey Bieber shared in a new interview that she hid her pregnancy for six months because her bump “stayed small for a long time.”

The model, 27, told W magazine in a cover story published Tuesday that she “probably could have hid [the news] until the end.”

The model told W magazine her bump “stayed small” for six months.

She wore “big jackets” before announcing in May.

She added, “I didn’t have a belly, really, until I was six months pregnant, which was when I announced it. I was able to wear big jackets and stuff.”

However, Bieber “didn’t enjoy the stress of not being able to enjoy [her] pregnancy outwardly.”

She recalled, “I felt like I was hiding this big secret, and it didn’t feel good. I wanted the freedom to go out and live my life.”

She said, “I wanted the freedom to go out and live my life.”

The Rhode founder and her husband, Justin Bieber, announced in May that they were starting a family.

Hailey debuted her budding belly in photos from her and the “Baby” singer’s vow renewal in Hawaii.

The couple has been married since September 2018, and the expectant star is “soak[ing] in” their time together before becoming a party of three.

“In the beginning [of pregnancy], it was super emotional for me,” she told the mag. “Like, ‘I love this human so much. How can I possibly bring someone else into this?’”

Hailey admitted that she is “not super close” with her family and instead feels “very independent.”

She said, “I’m my own individual now, and I’ve built my own family.”

Hailey married the singer in 2018, with the couple renewing their vows this year.

Before her little one arrives, Hailey detailed her pregnancy symptoms to W, joking that she wants to “change the name” of morning sickness.

The former “Drop the Mic” co-host went on to say that “the internet is a scary place for a pregnant woman.”

She explained, “You see so many stories — traumatic birth stories, traumatic experiences — and I know that that’s very real. But I don’t want to scare myself.”
