Hilary Duff threw a baby shower for her sister at the weekend. The actress teamed up with her mother Susan Colleen to invite around 40 friends and family members to celebrate older sibling Haylie Duff impending new arrival, and the mother-to-be had the "best day". She wrote on Instagram: "Had the best day celebrating our baby. Coco chillin in my flower crown...#MHBabyLove. (sic)" The celebration took place at Hilary's house on Saturday. And the group also enjoyed using a floral station, where they crafted bouquets in mason jars and made garlands for their hair. Hilary tweeted afterwards: "Sissy @haylieduff you are the most beautiful sister/mom to be and I love you so much! Happy baby shower day! Thank you to so many for coming and a big thanks to @donatiennela @hannahskvarla @ashleybeverly @thecrowncollective @lowenban @realjoseph #mhbabylove (sic)".
