Sept. 14 (UPI) -- Namibian-born model Behati Prinsloo is going to be a mom of two.
"ROUND 2....." she captioned a picture on Instagram of herself showing off her growing belly.
Prinsloo and Levine are already parents to daughter Dusty Rose, who turns one year old Sept. 21. Sources told People the couple are "so happy" to expand their family.
"Adam and Behati are so happy to be adding another baby to their family," an insider said. "They're amazing parents and their loved ones are thrilled for them."
Prinsloo married Levine in San José del Cabo, Mexico, in July 2014 after two years of dating. She discussed the most surprising aspect of becoming a mom in an interview with People in August.
"I think the fact that you could love a person more than you thought," the star told the magazine.
"I love Adam, and when you get married and fall in love with someone, you think that there's no greater love than that love," she explained. "And then you have a baby, and it's just next-level love."
