High School Musical star Ashley Tisdale threw a star-studded baby shower for her sister earlier this month (09Jan10) - with guests including Vanessa Hudgens and Haylie Duff turning out to celebrate the imminent arrival.
Tisdale's elder sibling Jennifer, 28, is expecting her first child with her husband, restaurant manager Shane MCChesnie, later this month (Jan10).
And her famous sister, 24, was on hand to organise a pre-birth party at her luxurious Los Angeles mansion on 09 January (10) in honour of the mum-to-be.
Tisdale's High School Musical co-star Hudgens turned out for the bash, along with Duff who became pals with the actress after moving in to the house next door.
Jennifer has already found out she is expecting a baby girl, and has named her unborn daughter Mikayla Dawn.
