Fans of Hilary Duff were given a sweet treat yesterday when she posted a picture of her newborn son on her Twitter account.

Prior to that, the singer posted a picture of baby Luca Cruz Comrie's feet saying it was her "favorite little feet." Hilary surprised her fans again when she posted the first official photo of her two-week-old baby boy.

Her adorable little boy was wrapped around a blanket while gazing at the camera. Luca seems to have gotten his beaming blue gray eyes from her mom. Hilary posted the picture on her website along with a caption that says, "Baby Luca, 2 weeks old :)"

Apart from her joy, the 24-year-old mother admitted that she is finding it difficult to get back in shape after giving birth to Luca just last month. Based on what she posted on her Twitter account, she says, "20 minutes on the elliptical seems like an eternity!!! What the hell..."

The former Disney star has been making jokes with her fans around Twitter regarding her post-baby body. She was then spotted out last weekend proudly sporting her added curves.

Hilary is wife to 31-year-old hockey player Mike Comrie. She gave birth to her first child Luca on March 20 and has remained honest on how she finds motherhood.

"1st outing complete with no tears! Made it home early...just in time to feed Luca. figuring this motherhood thing out! Yay!" Hilary said on stepping out again the first time, seven days after giving birth to Luca.
