"She loves monkey sounds," proud dad Berkus told Us of his little girl's milestones. "Pooping and eating - that's all she's doing. We're so completely in love with her."

Berkus and Brent, who announced they were expecting in September 2014, were married at New York City's famed public library in May 2014 during a ceremony officiated by the Oprah Winfrey Network's Sheri Salata. Berkus' mentor, Winfrey, singer Estelle, and Dr. Mehmet Oz attended the nuptials.
