Hilary Duff may be a smiling new mom, but it looks like baby Luca has something to cry about.
The former Disney star took to Twitter Tuesday night to post a photo of her adorable three-month-old son, but the crying baby seemed none too pleased.

Despite a kiss from mom, Luca put on a pout as Duff snapped the cute photo.
"I sent my dad this pic and he said 'Luca told me to tell you, you made this oatmeal lumpy,'" Duff tweeted. "lol he is cute when he's mad."
This is not the first time the proud mama has posted photos of her blue-eyed bundle of joy on the social networking site.
The TwitPic-happy star regularly keeps her more than one million followers updated with images of her growing baby boy.
New mom Hilary Duff tweeted a photo of herself with son Luca perched on her lap on Mother's Day.

In May, the actress celebrated her first official Mother's Day by sharing a photo of her son sitting in her lap.
"Me and my beautiful boy! So much to be thankful for," she wrote.
Duff, 24, welcomed home baby Luca with husband Mike Comrie in March -- and it didn’t take long for her to introduce the happy newborn on Twitter.
