Hilary Duff got sent a box of baby goodies from Jessica Alba.

The 'Lizzie McGuire' star welcomed her son Luca into the world on March 20 and fellow celebrity mum Jessica surprised Hilary by mailing her a range of products from The Honest Company range.

A grateful Hilary took to her twitter page to thank the 'Sin City' star for her generosity, writing: "Thanks @honest & @jessicaalba for the box of goodies for Luca! The whole line looks amazing! Excited to try everything :) (sic)"

The Honest Company was launched by Jessica - who has two daughters, Honor Marie and Haven, with her husband Cash Warren - and her business partner Chris Gavigan in January 2012 and it sells a range of toxin-free household goods, nappies and body care products.

Hilary has been reading baby Luca - her son with her husband, retired ice hockey player Mike Comrie - some of her favourite children's books to get him off to sleep and she admits it's been great to revisit the stories as an adult.

The 24-year-old actress-and-singer tweeted: "It's wild to read all of these children's books again! So many of them relate to adult life ... deeep! Lol (sic)"

Since becoming a parent, Hilary has been keen to share her joy on twitter and posted the first picture of the tot on the micro-blogging site earlier this week.
