On Tuesday (Sept. 3), the couple announced the news on Instagram, with the model voicing her excitement. "Been sitting here trying to come up with one of those long deep captions but honestly I'm so bad at that," Bailey wrote. "All I know is we are super excited for our little girl to get here." The "Don't" crooner seconded his girlfriend's post with a happy comment of his own, writing: "cant wait for my lil cocoa bean."
The pair were spotted together celebrating the news among family and friends, as pink and white balloons adorned the area.
For Tiller, this will be his second child. Harley Loraine Tiller, his first, was born in 2013 and is from a previous relationship.
