Adam Levine celebrated his daughter Dusty Rose's first birthday over the weekend.

The 38-year-old "The Voice" coach and pregnant wife Behati Prinsloo threw their daughter a colorful party featuring enormous unicorn balloons.

"We made it once around the sun.... @adamlevine," Prinsloo captioned a photo Saturday on Instagram of herself and Levine posing with the balloons.

"Not sure who enjoyed these wise old unicorns more, me or the kids. Thank you @johnalfordballoons," she added.

Dusty officially turned one year old Thursday, Sept. 21. Her birthday celebration followed news Prinsloo is pregnant and expecting another baby with Levine.

"ROUND 2....." the 28-year-old model announced alongside a picture of her baby bump this month.

Entertainment Tonight subsequently reported Levine and Prinsloo are "over the moon" to welcome another child.

"He and Behati want lots of kids, and they want them close in age," a source said. "Adam is over the moon, as is Behati. They are in love with Dusty and can't wait to make her a big sister."
