Get ready for a whole lotta adorableness.

New mom Hilary Duff tweeted a photo, taken by photographer Jennifer Wilson, of her baby boy, Luca Cruz, Tuesday to mark his 2-week birthday.

Duff shared a photo of his itty-bitty feet Monday, but this is the first photo of Luca since Duff and her husband, Mike Comrie, welcomed him on March 20.

"1st outing complete with no tears!Made it home early...just in time to feed Luca.figuring this motherhood thing out!" she tweeted March 28.
