Jessica Simpson

The singer turned fashion mogul made an appearance on the program to celebrate the 10th anniversary of her mega-successful clothing brand and made a shocking admission about her former marriage to Nick Lachey.

When Evans asked Simpson what she thinks have been her biggest financial mistakes thus far, the mother of two replied, "The biggest money mistakes? I don't know. For some reason I thought of my first marriage!"

Yikes! Evans chimed in with, "That's actually a common answer, believe it or not."

"I would like to apologize to my husband. This was not planned. I'm just so hormonal. Everything is great, I haven't vomited yet. That's a win y'all," the "Heartbeat Song" singer quipped in revealing that baby No. 2 with hubby Brandon Blackstock is on the way!

So her fans were treated to an unexpected treat along with all the goodness they expected from a Kelly concert.

But she's hardly the only one who took the opportunity to share some of the best news life has to offer with thousands of her nearest and dearest all at once.
