Telling your co-workers that you're pregnant can be complicated, which may be why baker Heather chose to just slide it into a random conversation on 'Cake Boss: Next Great Baker' (Mon., 9PM ET on TLC) rather than make a big announcement.

Her co-workers were totally unaware that she was pregnant until she said she had to go to the bathroom: "Baby pressing on bladder, I'll go really really fast."

Those chef's whites must be very forgiving as, unbelievably, Heather had made it to seven months' pregnant without anyone noticing. Except Chad, who said that he thought she was, but didn't mention it just in case she wasn't.

The 'Cake Boss' Buddy Valastro returned with the second season of 'Next Great Baker' (Mon., 9PM ET on TLC). At stake is an apprenticeship at Valastro's bakery, so he's very invested in making the right choices as the competition progresses.

!!SPOILER ALERT!!

Sometimes that means looking beyond the final product to the individuals behind the efforts. For the elimination challenge, they were separated into teams, which would test their teamwork. As they each have their own artistic vision, this was a tremendous challenge. And with a four-foot tall cake to create, they had their work cut out for them.
