Lily Aldridge just made our Monday morning brighter with the news of her second pregnancy!
The Sports Illustrated Swimsuit model announced that she’s expecting baby number two with husband and Kings of Leon singer, Caleb Followill, in an Instagram post that fully displays her growing belly.
In the photo, Lily snaps a selfie while wearing a bikini, which bares her tiny bump. “SURPRISE,” she captioned the shot.
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.
