Okay, come on ... are Justin and Hailey expecting a baby or what?!

There have been rumors -- and we've heard our own -- that Justin proposed to Hailey because she was with child and that the couple was spotted in a Brooklyn park a few weeks ago crying and hugging because (it's horrible) they lost that child. But who knows what's true -- what we know is that Hailey's been to the same Beverly Hills doctor twice this week and this time Justin came along!

The newly-engaged couple were in high spirits as they walked from their hotel to the office -- smiling and stopping to chat with fans and paparazzi alike. And since they were in such a generous mood, we decided to ask if they were headed to an ultrasound appointment ... of course! What else would you ask?!
