Behati Prinsloo Shows Off Baby Bump in New Photo, Chrissy Teigen Reveals Baby Luna's Nickname

The 26-year-old Victoria's Secret model, who is expecting her first child with husband Adam Levine, put on a bikini and took to Instagram on Wednesday to share an adorable photo of her growing belly.

"So far so good," she captioned the black-and-white mirror selfie. "Apparently I've swallowed a bell pepper this week..." According to a few websites, a fetus 18 weeks along is comparable to the size of a bell pepper, which may explain her reference to the vegetable.

The snap comes just four days after Prinsloo posted a pic of her rocking her first pair of maternity jeans.

"Yup took the plunge," the Namibian model captioned the pic, which has since been deleted. "First pair of maternity jeans and it feels so good."

She re-posted it in collage form, however, simply captioning it with a baby emoji the second time around.

Earlier this month, Levine, 37, made his first public statement that his wife was pregnant. He shared a sweet snap of her posing in a bikini (the same one she wore in her latest pic!) and a Los Angeles Lakers cap while relaxing by the pool via Instagram.

"My two favorite Laker fans," the Maroon 5 frontman wrote, with baby, milk bottle and basketball emojis.
