Behati Prinsloo was feeling grateful for husband Adam Levine on Father's Day. The 29-year-old model shared a sweet post and a first photo of daughter Gio's face while celebrating the occasion Sunday. Prinsloo posted a picture on Instagram of "The Voice" coach holding baby Gio. The couple are also parents to 20-month-old daughter Dusty Rose. "My first baby holding OUR second baby....." Prinsloo captioned the post. "Our girls are so lucky to call you dad and I'm so lucky to have you as a husband a lover and a friend. We love you. Life is better with you." "To my dad, thank you for being the best example to show me what i would want in a husband and father one day, the way you look at mom is the way Adam looks at me," she added. "Thank you for being the best dad EVER. Prinsloo gave birth to Gio in February. Levine said in an interview with "The Ellen DeGeneres Show" in May that Dusty is "obsessed" with her younger sister. "It's really cute. She's totally in love with her," the Maroon 5 singer said. "She's a little rough with her because she doesn't understand, so she'll get in her face and do crazy stuff, but it's just so much fun. Being a dad is the most fun thing on the planet," he gushed.
