Lily Aldridge and husband Caleb Followill announced an adorable surprise on Sunday — they're expecting their second child! The Victoria's Secret supermodel shared the good news on Instagram with a photo of her growing baby bump and plenty of smiley emoji. Lily, 32, gave birth to their first child, Dixie, back in June 2012. Since then, she's posted a ton of snaps of her sweet home life with her daughter and the Kings of Leon frontman, so we can only imagine how cute things are going to be when they welcome a new little one into their lives.
