It's a party of five for Adam Levine and wife Behati Prinsloo. The former Victoria's Secret model gave birth to the couple's third child, according to reports. Levine and Prinsloo's new addition joins big sisters Dusty Rose, 6, and Gio Grace, 4. The model had documented her pregnancy on Instagram in recent months, sharing pics from artistic maternity photo shoots. Levine and Prinsloo have been married since 2014 and live with their kids in California. The couple bought a sprawling estate in the posh town of Montecito, near Santa Barbara earlier this year, after selling a previous home in the Los Angeles area for $51 million. The pair's relationship hit an obstacle in September, just days after Prinsloo confirmed her pregnancy on social media. A source close to the couple told in September that while Behati was "upset" with Levine, "she does believe him that there was no physical affair." The insider added, "They have been together this entire time. She feels they are happily married and is shocked to find out what was going on behind her back."
