Wow! Look how much baby Bronx has grown! We snapped Ashlee and Pete arriving to their hotel after a long night out carrying their adorable little boy. The couple hit up the U.S. Open last night as Roger Federer defeated Jurgen Melzer. Ashlee allegedly spent the match drinking and got increasingly animated as the match wore on. It even looks like Pete had to carefully walk both his baby and his baby mama back to the room. Good think they took a taxi! We think he looks more like Ashlee, what say you?
