This star has just revealed she is expecting her first baby

Hayden Panettiere has finally admitted that she is pregnant!

The actress has been very tight lipped on the subject since speculation began, although her visible bump had given her away some time ago.

Now it seems as if the star is finally ready to reveal to the world that she is expecting her first child – and what better way to do it than with an ice bucket challenge?!

Hayden’s ice bucket challenge was shared on Twitter and Instagram by her friend, Derek Hough who wrote: “Couldn’t figure out hoe to post it on @haydenpanettier twitter so I’m posting it for her #als #icebucketchallenge (Hayden shortly went into labour after this) Jus kiddin.”

Hmm, judging by Derek’s joke, the actress must be due sometime soon – how exciting!

Hayden also confirmed the news herself in the video, saying among the names she nominates: “my unborn child” before being doused in ice cold water.

This will be the first child for Hayden and her partner, Wladimir Klitschko, who became engaged in October of last year. 

Congratulations to the happy couple on this news, we're sure they are super excited about their growing family! 

Today is also the actress' 25th birthday so we hope she is being spoilt rotten! Happy Birthday Hayden!
