Kelly Ripa

Kelly Ripa made a splash online this week when she tweeted a photo of her rock-hard abs.

Everybody's posing nude!

"Thank you @AKTINMOTION and @TheKaiserTweet for letting me lean on you," the Live! With Kelly and Michael co-host, 41, wrote, giving a shout-out to her trainer, Anna Kaiser, and her famous fitness method, which combines  "cardio, strength training, toning and stretching."

Ripa's bod is impressive considering she's already had three children. What do you think of the photo?
