Hilary Duff posts teaser picture of son Luca Cruz on Twitter
While she is waiting to share images of her newborn son with the world, the singer and actress gave fans a glimpse of her first child's feet.
The star, who gave birth to the boy last month, posted the image on the micro-blogging website with a short and sweet caption.
She wrote: "My favourite little feet."
Duff has also openly made fun of her increased frame via the social networking channel.
The 24-year-old tweeted: "20 minutes on the elliptical seems like an eternity!!! What the hell..."
When a follower congratulated her on looking good shortly after giving birth, Duff - who is married to sportsman Mike Comrie - wrote: "You should have seen what I looked like last week.
"Eek surprised I still have a husband!! It was time to throw them heels on ;) guurl."
