Her supermodel friends immediately flooded the mama-to-be’s comments section, leaving sweet messages of support. “Yayyyyyyy,” Kendall Jenner wrote alongside a few heart emojis. Meanwhile, Karlie Kloss added: “So excited for you mama lily!!!!!”
Nick Jonas even took time from his engagement celebrations with Priyanka Chopra to congratulate his friend in the form of two praise hand emojis.
Lily and Caleb are already parents to six-year-old daughter Dixie, who Lily revealed “is my best friend and the only person that I want to hang out with” in an interview with Porter.
“I am so proud to be a mom; it’s the greatest achievement in my life without a doubt,” she added.
Looks like Lily and Dixie will have to make room for one more in their BFF circle.
