Pregnant Olivia Culpo thinks she is expecting a baby boy

In a video posted to TikTok, she joked about "old wives' tales" and then signalled to the fact that her heart rate is below 140, which supposedly means that the baby is a boy.

Last week, Olivia shared two black and white photos from a maternity photoshoot, which showed off her growing bump in a flowing dress, on Instagram along with the caption: "Next chapter, motherhood [white heart emoji] (sic)"

Olivia previously hailed the NHL star as her "best friend"

She gushed to People magazine ahead of their big day: "I'm looking forward to marrying my best friend.

"I'm very excited for that next chapter, and I feel very lucky. He's a great guy."

The brunette beauty wore a conservative, long-sleeve Dolce and Gabbana gown for the wedding and despite receiving criticism for her choice, she previously explained she chose something "simple" to highlight the seriousness of her commitment to Christian.

She explained to Vogue magazine: "I didn't want it to exude sex in any way, shape, or form. I wanted it to feel effortless and as if it's complimenting me, not overpowering me. There's so much beauty and simplicity.

"It was exactly the same as the original sketch. This is the first, last, and only wedding dress I tried on.

"When I think about Christian and what he loves and the moments that he thinks that I'm most beautiful, it's absolutely in something like this: timeless, covered, and elegant."
