Spencer Pratt Won't Let New Fatherhood Get in the Way of Insulting Lauren Conrad

Spencer Pratt may have just welcomed a son into the world, but that hasn't stopped him from continuing his years-long streak of pettiness when it comes to jabbing at his wife Heidi Pratt's former Hills rival Lauren Conrad.

According to E! News, Spencer made a rude comment on Twitter after Lauren posted this picture of her son Liam in a lamb suit at a pumpkin patch.

Who What Wear tweeted to ask if that was just the cutest thing ever.

And that's when Spencer (aka "Pratt Daddy") sprung into action.

He said yes, Lauren could have found a cuter Halloween outfit for her kid. Well, then.
