Kelly Clarkson's hormone-fueled baby reveal

Kelly Clarkson's only a few months along but she was already bursting with excitement last night—hence the big surprise midway through her concert at L.A.'s Staples Center.

"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.

1. Beyoncé's Red Carpet Confession: The night that Mrs. Shawn Carter hit the 2011 MTV Video Music Awards in a Grecian-cut gown that just skimmed her burgeoning baby bump and told reporters that she had a "surprise" will go down in history as one of the great pop-hip-hop royalty moments. Blue Ivy's mama couldn't keep her hand off her belly that night.

2. Kanye West Interrupts Himself: Not even Kim Kardashian may have known that her boyfriend was about to tell the world, via his perch on stage in Atlantic City, that they were going to be parents. The best part, though? True to form, he had to stop something midway through so he could get the last word in, insisting "stop the music, stop the music," while performing "Lost in the World."

3. Will Smith Lends a Hand: With his and Jada's baby-making days seemingly behind them (never say never...), the actor was serendipitously on hand to help Emily here share her happy news on social media. Perhaps she'll get to star in the sequel After Birth.

4. Naya Rivera Goes Classic Metaphor: The Glee star went with the timeless "bun in the oven" motif, always in fashion.

5. Look What the Keibler Elves Made: Stacy Keibler also went in the baked-goods direction, making her moment all the sweet.

6. Baby on Board, Bwa-ha-ha-ha-ha...: That presumably #nofilter sunset in the background gives Hilaria and Alec Baldwin's blessed event sort of a pagan-sacrifice vibe, but still...a sweet family moment!

7. If the Shoe Fits: This was a big step for Kelly Rowland, who never even officially confirmed her engagement or her marriage before sweetly revealing that she and hubby Tim Weatherspoon were expecting. Then it was open season on showing off her pregnancy bod and talking about impending motherhood, but for a while...the singer was the picture of discretion!

8. Preserving the Moment: Blake Lively keeps fans abreast of her lifestyle choices on her website, and the decision to become a mother was no exception!

9. Life's a Beach: Nick and Vanessa Lachey wanted to put something down in writing when they learned that Camden was getting a little sister.

10. All in the Family: Carrie Underwood made sure that her firstborns, beloved pups Ace and Penny, were in on the announcement when she revealed (on Labor Day, no less!) that her first child was on the way.

11. Mummy's the Word: Perhaps one of the first major, fairly creative celebrity pregnancy reveals on social media, Jessica Simpson put her characteristically playful spin on the proceedings when she confirmed what was the worst-kept secret in Hollywood at the time.
