Lily Aldridge took her daughter, Dixie Followill, out for a stroll in NYC yesterday. The model looked cozy in black pants and a chunky sweater and alternated between pushing a stroller and carrying her little girl. Lily has been working steadily since giving birth to Dixie back in June 2012. She walked in the Victoria's Secret Fashion Show alongside her fellow sexy moms Adriana Lima and Alessandra Ambrosio and recently shot editorials for V magazine and Vogue while on the East Coast. Lily also kept busy this past weekend by throwing a surprise 31st birthday party for her husband, Kings of Leon frontman Caleb Followill. She tweeted fun photos of the celebration on her Twitter page, including sweet snaps of the couple and their friends.
